Ds is 13 week, sleeps in a sleeping bag and has a dummy. To settle himself to sleep he moves his head from side to side and rubs his forehead with his hands. Last few nights he has done this to 'settle' himself but it's taking a hour of replacing the dummy and him shuffling to get himself settled back down. Tonight I have been helping him settle since 1:05am and he's STILL shuffling 😩 has anyone got any tips, could it be part of the 4th leap? Early 4m sleep regression? Help!!
