Before one of our breastfeeding sessions, I noticed that my 3-month-old has a blister on his lip. What should I do?

Baby blisters on lips are caused by frequent feedings or vigorous sucking; they may also be born with it due to thumb sucking in the womb. It is perfectly normal and should go away after every feeding or lasting varying from weeks to months. They should go away for good after a few months. You don't have to do anything to the blister because it doesn't really hurt or harm your baby in any way. It may seem unsightly and feels like it hurts but it doesn't. Frequent nursing may also keep the blister there more than you'd like it to be but it shouldn't bother you and stop you from breastfeeding. http://www.babycenter.in/x1016994/is-it-important-to-get-my-two-year-old-dewormed
