I just saw my pedi yesterday for our 2 month check up, my baby is 13 lbs and only breastfeeding, my pedi states that he is about 2 lbs over what he should be. He feeds about every two hours during the day and every three hours at night. He only eats for about 7 mins on one side each feeding. I cannot get him to eat longer or on the other side most of the time, although there is a rare occasion he will eat longer and from both sides with really no change in frequency of feeds. My pedi wants me to "get mean" and encourage him to stretch out between feeds by letting him fuss a little and distracting him. Is this normal? Should I just keep feeding him the same?
