Yes mine will just do it randomly. Wonder if it's related to teething...
mine doesn’t do it but i read that babies hit their head on the floor or with their hands because of how much babies get swung around in the womb they’re trying to reenact that and so it is just them trying to find that soothing feeling again
My little boy went through a phase of doing this! But he also had a few ear infections around the same time so likely to be related x
Yes very normal for this age
