4 month old dd hitting me in the face and pulling at my ear-rings, visciously! Why and what to do??

[peacelily]

She's just got quite violent in that when she gets frustrated or when I say no she'll practically punch me in the face. Also if I've just got in from work and am wearing ear-rings she'll try to pull them really hard!

When I say "no" in a firm voice and remove her hand she screams hysterically and throws herself on me sobbing?!?!! What do I do? And what am I doing wrong??

She actually really loves playing with my hair as in she pulls in down over my face (not hard) and when I blow it out of the way she laughs her little head off.

She's never tugeged at it or grabbed it in frustration like the face hitting thing just out of curiosity. She isn't as angry when playing with my hair!

Another funny but total no no of a behaviour is she's started pulling my top, down poking my boobs saying OOOH and laughing!! ( if she remembers Bf then she's got a good memory cos it was 8 months ago when she last had any!)

Late, way past bed time.

Thanx for the advice and reassurance xx
