Re: Food Allergy or Oversupply?
Welcome to the forum!
Figuring out what is causing any particular baby behavior or set of baby behaviors is always a challenge. It's especially challenging with a 3 week old baby, who has had so little time to establish any sort of pattern or to learn how to express what is troubling him, and who is changing all the time. So instead of worrying about foremilk/hindmilk imbalances or allergies, I'd consider a third possibility: that your baby's behavior is absolutely normal, and just a symptom of him being a very young baby. Most of what you describe is absolutely textbook normal. For example:
- Explosive yellow poops is normal. Breastfed babies can be expected to have very liquidy poops that kind of jet-propel themselves out of their rear ends.
- Having gas immediately or shortly after eating is normal. Eating activates something called the gastrocolic reflex- basically, putting something in at the top of the digestive system causes a person to move something out at the bottom end. This is why even adults often find themselves going to the bathroom right after a meal.
- Waking up or fussing when pooping or passing gas is totally normal for a new baby. Remember that up until 3 weeks ago, your baby never had to do either one of these things and now he's doing them all the time.
- Wanting to nurse when something upsetting is going on (e.g. pooping, passing gas). Babies don't just nurse because they are hungry. They nurse for comfort, and that's awesome, because it's really hard for a baby to cry when there's a breast in his mouth!
Some of what you describe- the coughing/gagging/clicking, the fast feedings, the baby wanting just one breast on a fairly frequent basis, the baby pulling off the breast- are quite suggestive of oversupply. But it's still very early days and I would encourage you to not go near block feeding just yet- block feeding is designed to reduce supply and .it's possible to go too far with it. Instead, try nursing in more reclined positions. That way gravity will work against the milk flow, which may make nursing more comfortable for the baby.
Now, if you reach 4-6 weeks and baby is still giving you lots of those oversupply/fast letdown symptoms, and reclined nursing clearly isn't enough to deal with it, then let us know and we'll walk you through block feeding. But give yourself a little more time before deciding it's necessary!
