I talk a lot about humans and kangaroos when supporting new parents. You see one of the few mammals who birth their babies at a more underdeveloped stage than us humans are kangaroos. Kangaroo babies crawl up into mum’s pouch and then latch on to the nipple and pretty much feed 24/7. Human babies, if left to their own devices after birth, crawl up their mum’s chest and then latch on to the breast. They then need to be fed very frequently. But unfortunately we don’t have a pouch. But we have strong arms, I nice curvy body to lie on and we can make a pouch by wrapping fabric to help our arms.
Humans are “carry” mammals. These include all the apes and marsupials. The “carry” mammals birth the most immature infants out of all the mammals. They are completely dependent on their mothers for food, warmth and safety. Our babies are fed frequently and because of this our milk has very low levels of fat and protein.
Other types of mammal are “follow” mammals such as horses and giraffes. These babies can walk soon after birth and feed quite frequently as they can keep up with their mothers. Their milk is a little higher in fat and protein than carry mammalsnas they feed a little less. “Nest” mammals such as dogs and cats leave their babies and return several times a day to feed. This means the milk needs to be higher in fat and protein to help them wait for their parents return. And then there are “cache” animals such as rabbits and deer. They leave their babies in a safe place and return every 12 hours or so to feed them. Consequently their milk is much higher in fat and protein in order to sustain them for long periods.
Many baby books seem to think we are nest animals. We aren’t. Human babies expect to be held constantly and fed frequently. Our milk is the perfect consistency for this. This is normal newborn behaviour.
When a baby or babies have arrived early, Mum often feel stressed and helpless and feel one of the few things they can do is to provide breast milk. Preterm breast milk is different to that of a mum who delivers at term. It has higher levels of energy, fats, protein, vitamins and minerals, and most importantly it has higher levels of immune factors. It is highly valued in the neonatal unit and mums are usually supported to hand express colostrum within the first 6 hours after birth, and then move onto the pump to provide breast milk for tube feeds. The hospital should be able to advise on renting a hospital grade double pump for when mum is discharged. It is important to pump frequently; we recommend 8-12 times in 24 hours making sure at least one is between 2-5am when hormone levels are at their highest. There will be a more detailed blog on establishing milk supply through pumping soon.
But what next? How do we go about actually breastfeeding? Is it possible to move to exclusively breastfeeding when you have had such a traumatic entrance to the world? The answer is yes, but it will take time.
Once premature babies hit around 32-33 weeks gestation they often begin to start developing a suck, swallow, breathe pattern in short bursts and may start rooting for the breast. Hopefully mum will have already been given the chance to have lots of kangaroo care with her baby before now, but at this point it can really help transition the baby from tube feeds onto breastfeeding.
Learning to breastfeed when you are a premature baby is a long, slow, tiring process and it requires everybody to have lots of patience. To start with babies can have skin to skin time, or kangaroo care, be encouraged to lick the nipple and if they are ready to possibly have a few sucks. A baby can begin with non-nutritive sucking at the mum’s recently pumped breast to provide a gentle experience without an overwhelming flow of milk. Then a fuller breast can be introduced. But at this early stage the majority of any feed will still be expressed milk through the feeding tube. The staff will encourage mum to maybe try baby once or twice a day at the breast so as not to tire them out too much. Once they become stronger and start to suck and swallow more efficiently its time to move to more frequent feeds. It can be a good plan to try baby at the breast during their tube feed as they will begin to associate the act of breastfeeding with the feeling of having a nice full tummy. A nipple shield can help the smaller baby to latch onto the breast, especially if they have been given bottles. There is evidence that suggests shields can incease milk intake in preterm infants in the early days. Remember ask for lots of support from the hospital staff during this time. This is actually one of the benefits of having babies in special care.
When the babies appear to be feeding better and getting much more milk we can move on to the next stage. This can be at different ages for different babies. For some it can be around the 36-37 week gestation mark, others need to get to near full term. The hospital staff will help give confidence that it is time to move to the next stage. Whilst some babies will be able to move straight on to exclusive breastfeeding from tube feeding, this new enthusiasm for feeding can be a bit misleading as the suck can still be uncoordinated and inefficient and the babies can still tire easily. If we move on to exclusive breastfeeding too quickly, it can cause problems with babies not taking enough milk, becoming too tired and then starting to reduce their weight gain. So for many babies its advisable to continue to top up with expressed for a while. A lot of mums choose to top up by a different method than tube so the babies can get home. Hospital staff may use a tool like the Breastfeeding Assessment Score below to calculate how much top up to give baby. They will calculate to work out exactly how much milk depending on baby’s weight, gestation, growth about how much a full feed is.
For twins and triplets it is important to remember that they are individuals. One baby may be much better at feeding than the other. It can be hard not to compare and be worried and frustrated if one baby is not managing to feed as well. But, with time, it is very likely that they will catch up and both will feed well from the breast when ready.
Generally hospitals prefer to use bottles to feed babies their top ups, or during the night when mum is not there. They are easier, there’s less waste and staff are pushed for time so go for the easier option. So to minimise the impact of using a bottle on breastfeeding, it is important to use a paced bottle feeding technique. Paced bottle feeding means letting the baby take control of the speed of the feed and when to take breaks and when to finish. Sit baby in an upright position and keep the bottle as horizontal as possible whilst still filling the teat with milk to avoid intake of air. Baby should be encouraged to latch on to the bottle like the breast, so touching the top lip to encourage baby to route and bring baby onto the bottle chin first, teat into the roof of the mouth. Stop frequently and make sure you do not force baby to have a certain amount. With this slower feeding technique, the baby will be able to tell it is full and finish the feed when satisfied. And baby will be more able to transfer between bottle and the slower flow of the breast.
Mum and baby will hopefully be given the chance to ‘room in’ for a night or two before they are discharged. During this time they’re often encouraged to move on to more baby-led feeding as opposed to hospital routine based feeding. But babies can still be sleepy and not wake for feeds at this stage so its important to make sure that they feed at least every 3 hours as a minimum. 3 hours is measured from the start of each feed.
For a lot of preemie mums, their first experience of being at home with their early baby is to be in an intense breastfeed, top up, express routine, every 3 hours or more, day and night. This is utterly exhausting and overwhelming and mums can often not see past this stage. However with good feeding support from health visitors and breastfeeding specialists and the discharge team from NICU, mums can move on to exclusive breastfeeding.
Whilst the baby still needs top ups it is imperative that there should be somebody to look after mum. This routine is so full on that there is not much time for anything else, especially sleep! Somebody to do the top up whilst mum expresses can be a life saver as this can save time and could give mum half an hour extra break before she has to start the process again. Breastfeeding makes you hungry and for mum’s energy levels it is important that she eats properly, so having someone to feed her whilst she feeds the babies is a great idea. Every single breastfeed given and every single drop of expressed milk should be valued and encouraged. Emotional support reassuring her that she is doing a brilliant job and that soon it will become much easier can keep everyone going through this incredibly tough time.
Support can be invaluable at this time but a lot of mums feel unsure about taking their preterm baby out to groups due to risk of infections. This is where home visits from well informed health care professionals and good online support can step in. Online support especially can be great, as long as it is properly moderated, as mums can make contact with others who have been in the same position or are going through it at the same time. Peer to peer support is incredibly important. There is also often somebody around at 3am during the night feeds to sympathise!
So how do we know when a baby is feeding well enough to move on from this routine? Often around due date or just after, babies suddenly ‘get’ feeding. Their suck becomes more coordinated and they can remove more milk from the breast. You can watch for the full term feeding pattern of sucking fast for a minute to stimulate the let down, and then move on to deep slower jaw movements with pauses in between. You may be able to hear swallowing. Breast compressions can help to get a bit more milk into the baby if they are still seeming a little inefficent or sleepy at the breast. They often have a big feeding frenzy at around due date and sometimes want to cluster feed. This can be very unnerving for a preterm mum who is used to having a sleepy baby who needs to be woken for feeds. Cluster feeding should be encouraged and explaining to mum that it is completely normal behaviour and will help baby get lots of milk. However it does not necessarily translate in to weight gain immediately. It can be very discouraging when baby has been feeding all night and only put on a small amount the next day. However you often find a day or two later and it pays off.
For twins or triplets it may be a good plan to get some support with tandem feeding. Tandem feeding maximizes the time spent feeding as there’s less waiting time for babies and it is a more efficient use of time. It helps synchronize the babies’ feeding times and more importantly sleeping times! A strong feeder can help a weak feeder by stimulating the let down and getting the milk flowing. It also increases milk supply and the milk has a higher fat content.
Dropping or reducing the top ups gradually can make it a bit less stressful. For more detailed info in reducing top ups see our other blog here
But here’s an overview: Mums can reduce the volume of top ups and put babies back on to the breast if not settled. Mums often find that babies are more settled during certain times of day or night and these can be the first feeds to just breastfeed. Encourage mums to allow the baby to have a second or third go on the breast if they do not settle after the first feed. Offer the other breast so baby gets a nice fast flow of milk. For twins or triplets you can just put them back on the same one and mum will get another let down of milk.
Aiming for maybe 3 top ups of expressed a day and being baby led in between is a good starting point. Mum can keep an eye on nappy output during this time to give her peace of mind and she may prefer to weigh the baby before moving on from this stage to give her confidence that everything is going well. Sometimes when babies move on to more direct breastfeeding, their weight gain can flatten off a little bit. This can be really discouraging but it can take a bit more energy to fully breastfeed and they can tire themselves out and burn more calories. As long as they are still gaining this is usually ok and they will set off following their curve again given a bit of time. This may be a good time to get some reassurance from a breastfeeding specialist.
Once mum is feeling confident and babies are feeding well it is relatively easy to drop the last few top ups. Mum can either stop them all at once or drop one at a time. It is often a relief to have the relative simplicity of just breastfeeding without all the faff of expressing and washing bottles. Some prefer to still keep an expressed feed in their routine so that they can have a break.
Breastfeeding is so important for babies, but even more so for premature babies. But establishing breastfeeding in the neonatal unit is like a marathon, not a sprint. It is a slow process taking every ounce of patience and determination. But it is worth every bit of stress.
