DS is just over 5 months now and he's just started hitting his head or pulling his hair while he is feeding or going to sleep, it's a constant fight to keep his arm down (boy babies are strong- thankfully I am still stronger) I don't know exactly when it started and it's not really hard at the moment but seems every day it gets a bit harder. He falls asleep shortly after. Anyone else have this problem? Have you been able to do anything about it? Or did it just stop?
