He bangs his head on the cot mattress to fall asleep. Every night now
Started about two weeks ago. He gets onto his hands and knees and rocks, and then thumps his forehead into the mattress, quite rhythmically, until he drops off. Five or ten minutes. He doesn't seem upset while he does it, and he's cheerful in the morning. Daycare says they haven't seen it at nap time. I work with children with additional needs all day, so of course my brain goes straight to every checklist I know. I'm trying to remember that a single habit at bedtime is not a checklist. Anyone else's baby do this? Did it stop by itself?
