Anyone else’s baby shake their head kind of vigorous now?

I notice it more when she’s falling asleep for the night.

Also bangs her head while in the high chair. Any ideas on how to get her to stop? I’m sure the nighttime is she’s tired but I don’t want her to hurt herself in the high chair. I already stop feeding and say “no” or “stop” and explain why. Is this just a phase?? FTM
