Squeezing eyes shut? Blinking hard? Then smiles?

My little girl was doing this for a few weeks! I think because we laughed when she did it she just did it more 😅. She’s stopped now though x

My little girl done this a while ago, shed also squeal sometimes while doing it lol its stopped but ive noticed her doing it again with the scrunched up face lol seems like an excitement thing so not too worried but also not sure if its normal haha x

My LB does the same . He is so cheeky 😁. Not worried at all , I think its normal. They are just trying things out
