My lo is 3.5 months and we are on the 4 hour EASY (doc suggested going to a 4 hour routine bc lo didn't seen hungry at 3 hours and was just snacking). For the past 3 weeks or so, he has been waking up at night very erratically. I posted something here and someone suggested feeding him because he was probably going through a growth spurt. So, for the past 5 days or so I've been feeding him and he will go back to sleep (after he takes a full feeding). How long are GS supposed to last? I really am scared that he will get dependent on the feed to go back to sleep. Any suggestions? Last night I tried not feeding him when he first woke up, around 245, but then he woke up every hour until I did feed him. Help!
