Sharing again.
This is a question that is asked a lot.
It's very common for babies to be fussy and unsettled at times, and even quite often in some cases.
But it may be unnerving for parents who become concerned that perhaps the baby isn't getting enough milk.
So a bottle is given to 'test' this theory and the baby wolfs it down and then crashes to sleep. Parents are left feeling utterly deflated that the they were letting their baby go hungry.
So why is it that those of us in the world of lactation say that drinking a bottle after a breastfeed isn't neccessarily sign that the baby was hungry?
To understand fully we need to look at two things, firstly normal behaviour at the breast, and secondly, normal response to a bottle.
Society would have us believe that babies latch onto the breast, feed and then settle. But that's not actually the case. There is usually quite a lot of fussing and bashing while they figure out where they're latching, then lots of quick sucks and tugging and hitting while they encourage your milk to let down. Then there is likely a period of calmer feeding while they have a good quantity of milk (look and listen for swallowing!) and then they may start to qet squirmy, tugging, gumming and hitting again as the flow slows down. This is all VERY normal behaviour.
Keep in mind in an evening, when most parents find their supply is running slower, and during growth spurts, babies will often be a lot more fussy at the breast, and that's ok too! Its stimulation behaviour to get the milk flowing. And the more milk that's removed, the more milk is replaced.
Babies have tiny tummies, digest breastmilk quickly, and use the breast for plenty of reasons other than food, so it's also very common for babies to decide that actually they would quite like to go back to the breast please, even though they had appeared to have finished not long before. Again, normal. (I didn't say easy, I said normal!)
Looking at all of the above, we can completely understand why parents may assume their baby is unhappy or not getting enough. Usually once they've had the information about it all they feel empowered to carry on the way they are.
But, if they don't have that information, they may carry on and give that bottle. So why would the baby take it?
Well, firstly, because babies love to suck. Its soothing and comforting and releases pain relieving hormones and means they are next to your body and in your arms. They're clever little creatures.
Plus, it's pretty easy to get a bottle teat into a baby's mouth, they barely need to open at all compared to latching at the breast.
But why once the teat is in do they drink? Well, sucking is a reflex that happens if something touches the back of the roof of the baby's mouth. So they can't actually help themselves.
When a baby feeds at the breast, sucking is only a part of it, the tongue compressing the breast against the roof of the mouth in a wave like motion moves the milk. But the feeding action with a bottle is very different. Even gentle sucks will cause milk to flow, and we've already seen that babies can't help but suck the teat, so end up with a mouth full of milk whether they want it or not. So they swallow, because once again it's a reflex in babies.
They end up sucking and swallowing until they're so exhausted that they stop.
By this point they're overly full and exhausted so their body shuts down to work on digesting the heavy meal.
So a baby will take a bottle because of their reflexes, not necessarily because they need it.
If they're doing plenty of wee and poo, and gaining weight as expected, there's no need to offer a bottle (unless you choose to). If you're concerned about your baby and feeding in any way get some skilled support to fully assess and reassure you that all is well. But try and trust your baby and trust your body, they know what they're doing x
