Talk to me about regression. Dd is 5.5 was toilet trained at 3 apart from the odd accident, she's now back in nappies. Her speech has never been great but now even my mum struggles to understand her. She's getting worse with personal space, pawing at people she doesnt know (children and adults). We're still on pathway but ive always know she was different. (I have 4 children, ds is diagnosed asd)
