Re: How many mL or oz should my 3 week old be eating? Is he getting enough?
You're doing a great job, mama!
Three weeks is prime time for a growth spurt. It's totally normal for him to be nursing much more frequently. In fact you WANT to put him to the breast as much as possible to tell your body to make more milk - that's what the growth spurt is all about. The worst thing you can do now is supplement with formula because your body won't get the "more milk" message. Your milk supply will adjust to meet his needs. Just nurse him.
Your baby is gaining steadily and well - ALL on your milk. What did the pediatrician say about his weight gain?
The BEST way to judge a baby's input (how much he's getting) is by keeping track of his output (counting diapers.) You want 6-7 wet diapers and 2-3 poopy diapers (with BMs the size of a quarter or larger).
Pumping is NOT an indicator of how much milk your baby is getting. Babies are MUCH more effective than an pump and many women don't let down for a pump like they do for a baby.
As for the baby drinking the bottle - that is NOT an indicator that he's still hungry. Babies will suck on a bottle and drink even if they are full.
While supplementing with formula isn't "bad" when necessary - it does NOT sound like you are in that situation. Introducing formula without the need for it can do serious damage to your milk supply.
Your baby is growing fine on your milk alone. His weight gain is good. Track his diapers to reassure yourself that he's getting enough. Trust your body to make the milk. Listen to your baby and nurse him on demand. This growth spurt will pass and everything will smooth back out.
And expect a few more growth spurts - often around 6 weeks, 3 mos, 6 mos.
You're doing GREAT!!! Keep it up.
