aves_y,
why you have to offer your bb with formular? stop pumping? not enough milk??
suggest you pump as much as possible, you can pump one side and feed another side to increase more stock.
i think the reason why your bb vomits:
1) maybe he is against the formular, since he loves
breastmilk more.
2) he is allergic to cow milk , means cow milk(formular ) is not suitable for him.
aves_y,
Your bb was the same as TIm when I fed him with 2 oz (he was around 1.5 months old at that time) THe 1 st time he threw up , I thought it as normal. At 2nd time, he threw up after taking Enfamil for 4 hours!! HE turned pale after that and could not drink milk well for the whole night ar. I was so worried and guilty. Originally, I let him try Enfamil because I was afriad that I could not have enough milk for him after going back to work. VIewing his problem upon trying formular, I did not feed him any. Rather I tried my best to bf totally.
Now, he is 8 months old already, I am proud that he has been bf totally by me. And I won't stop bf until natural weaning.
So, if your pbm is just worry about the supply, try other methods to increase your stocks instead of stopping breastfeeding.
