Sometimes I do, but it takes him a long time to burp on 2.5oz or less. However, 3 oz or more he burps almost instantly after finishing.
I would try a new formula, he probably has acid reflux. Talk to your pediatrician bc a 3 month old should be able to handle 6-7 ounces at a time.
@Chelsea didnt think of that...i had switched him to plant base temporarily until we get his congestion under control. 6-7 oz how many hours apart...he does 3.5 every 2 hours...
Do you ever burp him during the feeding?
