Girls, it's been three months and a week. The baby has become very fussy, he doesn't sleep without crying, wakes up every 5-10 minutes with a cry. When awake everything is fine, but when he wants to sleep, he pulls at his ear, scratches his head and bites. Has anyone experienced this? I attached a photo, if you have any video suggestions please let me know.
