My 16 week old still has jerky movements - I'm a first time mum and getting abit worried as I thought these were meant to go by now?
He can grab things and bring them to his mouth but sometimes he will literally slam his arms downs down etc... And in the bath he does it more. He does so fluid moments when he rubs his eyes and rubs his head etc it's maybe more when he's excited or frustrated. Is this normal?
