my bb also didn't like drinking milk when he was 2mths old... if your bb looks happy, healthy, & can play, then don't worry coz there's nth you can do... my bb is now 6mths old & he still sometimes refuse to eat beyond 2oz.. (sometimes finishes 6oz...)...
My baby now is 4 months and she has the same situation 2 wks ago, reject to drink which only take 3time with 5oz per day. But the Dr mentioned no problem if she have grown well and heathly.
Start from last week, she suddenly recovered and willing to drink now.
