DD has started to..... how shall I say...... protest(?) somewhat to things that she seems to dislike.

Screaming (not her hungry or tired cry - I KNOW these ones), arching her back, kicking her legs, digging her heels into the ground etc.

Is she too young for tantrums? How do I handle them at this young age if that is what they are?

For example. I know when she is overtired. So we are lying down feeding to sleep, she starts screaming at me and arching backwards. I have been talking really gently to her and holding onto her firmly - she does settle down when I do this. Is this the right thing? Or should I let her thrash around for a bit?

Pfttt, I had no idea I'd be asking this question so early on.
