My 3.4 yo DD developed a blinking tic. It seems the strongest when she watches telly before the bath time, for the rest of the day it hardly noticable. It started with the new arrival of a baby brother, which I thought she's actually taking very well.
I had a look on internet, and it seems that motor tics are quite common, and usually go away within a few weeks without any intervention. Noone actually says what causes it - is it because she's upset about the new arrival?
Does anyone has any experience? I haven't seen any posts about it, so maybe is not as common as they say?
