My daughter screws up her face or makes faces randomly I’ve always thought it was just normal
It’s only come on in the last week which is why I’m questioning it, I think if she’d done it forever I would have thought it would be more normal but she probably does it 20 times a day
She might’ve just learnt she can do it. When my daughter learns a new skill like blowing a raspberry, sticking her tongue out etc, it’s all she’ll do until she learns something else! Almost like practicing.
Babies just pull all types of faces nothing to be worried about, they’re exploring and learning new things and maybe she’s just learnt a new expression.
My son does this exact thing too, not sure what it is but hopefully someone else knows. I chalked it up to surprise or excitement too
