I know this should technically be posted in special needs but I could do with the traffic here as I know there are lots of experienced parents of children with ADD here.
DD is 4 and under assessment for ASD. She doesn't particularly 'play', she likes to arrange her toys and then leave them and doesn't want anyone to disrupt them. She will arrange her dolls house and then be hysterical if one of her siblings enters the room in case they move anything. Obviously it can't stay untouched forever so I offer to take a photo so she can remember the arrangement. This sometimes works. She will receive toys for birthdays/Christmases/her pocket money but hoard them in her bed in case anyone disrupts them.
She has to share a bedroom with her 3 year old sibling which makes things very difficult. Has anyone experienced similar behaviour? Any advice would be much appreciated.
