Is anyone’s else’s baby moving his head side to side? He started this last week and does it quite frequently. He mostly does it when placed down in a new area or he hears a new voice almost as if he is trying to look around but he is shaking his head side to side way to fast to actually see anything. I’m waiting for his two month appt to ask the pediatrician about it but was wondering if anyone else has seen something similar? He is 8 weeks old today.
