I think it’s a normal part of their development! Mine does it sometimes and sometimes does it to say no
Yes it’s normal. It’s part of learning how to control how their bodies can move in different ways. My LO has also now realised he can do it to music and we smile at him 😂 x
My baby does it all the time and sees it as a game, he waits for us to shake our head back and then laughs and repeats 😂
My baby does this too especially to some nursery rhymes as if enjoying the music. So i think it should be normal
Don’t know if it’s normal but my baby does this too but smiles/laughs whilst doing it. I just took it as he’s learnt a new trick and thinks it’s funny. Hopefully it’s no concern☺️
