Babies hitting out

Khloie 🇬🇧 • Baby boy 10th Dec ‘17 🐒 Baby girl Aug ‘19 🤱🏼

Has anyone else’s baby recently started hitting out at you? Mine is doing all kinds including biting which I didn’t think was in a malicious way but now he knows what no means and continues to do it. He’s also pinching and slapping.

How do we deal with this???
