DD4 is super sensitive to everything. She has loads of sensory issues and barely eats. She's never shown any affection, hates being touched, screams the house down during hair and teeth brushing, has to have a very set routine, collects and hoards things etc. She's extremely careful and anxious, has no tact whatsoever and prefers to be alone.
DD2 can only say mum. She has to be watched constantly as she's always climbing and putting everything in her mouth. She is overly affectionate and climbs all over me and her siblings. She dislikes other children immensely; she will screech at and push them if they get within reach of her. She gets extremely angry and will bite whatever is to hand while screeching, shaking and going red in the face. She is not intense in the way her sister was but is intense in that she has to be watched constantly to stop her hurting herself or others. She is due a SALT review next month and I discussed raising the possibility of autism with DH but he thinks it can't be as she's so different to DD4. Do you think it could be a possibility here?
