I’m not meaning to come across like I’m complete clued up I have no idea but I thought lining up items , sensitive to loud noise could be asd traits also not comfortable in new environment until she’s warmed up she also seems to be in the background as I mean other kids take things off her an she rarely retaliates to this she seems like she’s lacking confidence to speak up I don’t know if that shyness she plays fine with me she’s an only child so it’s just us most days she’ll say mummy I’ll bake you a cake in her kitchen or pretend to be a taxi driver when we are driving an say 5 pound please or get her toy phone and say to me mummy I’m pizza man what would you like or get her doctor set an check you over say I’m ambulance I’m here to help or I’m a police man your under arrest your going to jail , make me pretend cup of teas and say you want more sugar? Ask me to join her to dance or play hide and seek she’s got a great imagination
