She is a very clever little girl but also very determined and has a bit of a temper!
She is walking about and is fine when she is going where she wants to go, if you try and get her to go in another direction she literally throws herself on the floor deliberately banging her head and screaming. If you really won't let her do something she starts hitting herself on the head and screaming! She also head bangs things too if she can't get her own way.
Is this normal behaviour for a baby so young?
