For the last 3weeks, 20mth old DD appears to have been struggling with some kind of sensory problem relating to her feet. She is suddenly terrified of walking on grass or putting her feet in sand or water. In fact she refuses to be barefoot at all. It's like it terrifies her. She has also started to touch things with her feet in a strange way. She also screams if you stroke or rub them which is something she used to love. She only ever walks on tiptoes now.
I took her to the GP last week to check she hadn't hurt them in any way and he thought they were fine and suggested it may be just taking her longer to recover from the very nasty virus she had last month (she ended up in hospital)
I did a search on here and it seems that it's closely linked with autism. I have to say I've never had any cause to think she's autistic. She has very good understanding, copies, points and talks in 3 or 4 word sentences. She also has imaginative play (e.g puts her dolls down for a nap) But what worries me is all the threads on here where people link it with regression. Is it common for a 20mth old with good understanding and good, appropriate speech to regress? Could the virus have triggered something?
Are there lots of other causes for the problems she seems to be experiencing? I'd be grateful for any advice please as I'm really starting to worry.
