hello, dd almost 17months old has started doing a very odd thing throughout the day, she sort of freezes, clenches her hands and teeth and trembles!!! I think it's excitement, but i'm a bit perplexed -
I have vague memories of my sister doing this when we were small, but dd seems to do it for seemingly not that exciting things (although they must be to her!) Please can anyone shed light on this?
TIA
