My Daughter has just turned one but for a few months now when she is in her highchair, on her trike or sitting on someone's knee she starts to grind/rub her bum in her nappy, she goes into a trance. She can be distracted and it doesn't last very long. I have had a text from her child minder to say it is something she would mention at her 12month review, which is tomorrow. I have now google'd it and some sites say it can be a sign of autism although she isn't showing any other traits and as I say she can be distracted from doing it............Any ideas anyone?! Should I mention it tomorrow?
