Sounds very similar to Ash!
Ash can be quite stubborn now. Really stubborn.
We used to have huge play ups after bath and with bed, she would get so silly but has settled now.
She often likes to pretend she is a baby to copy Emily so sucks on toys, crawls around.
Makes up pretend people and pretend words.
I hate the "I want" too or :mummy get me my water." hmmm no how about we ask nicely then she clamps her mouth shut and sits grumpily.
