Biting baby

[Meepmoop]

Hello,

My DS is 8 months and he keeps biting me. He doesn't bite when feeding thankfully but bites my arm,legs anything.
His favourite thing to do is grab my hair either side of my face pulling me in and biting my chin.

Is there anything I can do to stop him doing it I suspect he's too young but it's really annoying. I've tried a firm no but he just laughs at me (its annoyingly cute)

Thank you

Dd 9 months did it to me twice- each time I did my best stern face/teacher voice and said "no!" A couple of times and it did work and she hasnt done it since. I think it is about keeping your face straight- if you start smiling or laughing they see it as a joke! It is really hard though!!
