Ugh my son recently went through the 3/4 regression and was doing well for a few weeks and now is having issues again at 4.5 months! He has a consistent schedule and puts himself to sleep at night, but has been having night wakings 2-3 times a night before his night feeding time. I don’t give in and feed him and don’t pick him up I just go in at certain times and touch his chest etc. last night he has been upset off and on whining for 1 hour!! Just venting and looking for consistency :( Any of you going through this?
