DS is 10YO and has been diagnosed with Autism. He is statemented at school. He gets DLA. So we know the signs.
Anyway DD2 is showing signs, but she is only 3YO. We are not sure if we should go to the GP about starting to look into it. We had hoped that when we took her to the speech therapist (as advised by preschool due to her never saying a word for the first couple of months) it would be the start of a similar process that we had for DS. However, she started talking more. The Speech Therapist said that while she was behind, she wasn't so far behind that it was a worry. So now they have backed out.
Anyway we are convinced that there are signs there. Refuses to wear pants (she says she will be in nappies when she's an adult), hates loud noises (got upset by a car alarm on Friday night at the opposite end of the car park - DS wasn't bothered), hates change of plans (she had a meltdown when I popped to Tesco and not Morrisons because I had said we were going to Morrisons - I decided when I was in the car to go to Tesco instead), she lines things up and everything has to be just right (meltdown occurs if her curtains aren't shut right when she goes to bed - the left curtain has to be over the right curtain where they meet instead of the opposite)
There are other signs too.
We are wondering if we should look to get DD2 looked at or is it possible that things will come to light anyway? She will be 4 in September so she's just over 3 and half ie not just turned 3.
