DS whos ASD has 2 siblings older one brother one sister , DD is 14 and quite calm and understanding with DS but DS1 whos 15 is not helpful at all he moans at him brings on DS2's meltdowns as he doesnt get it at all ive explained the traits and his foibols to him till blue in the face, i praise all 3 of them and sit and chat about their day ect ect but hes so typical teen cant be asked to do anything he refuses flatly to read up on ASD hes a very loving lad i just think his brother gets on his nerves (hes like a shaddow) and needs space ive suggested although moneys tight atm separate days out with dad /me so they can get a bit of attention but i do feel hes jealous and not being a kind big bro like he should be hes just i hope going through being a teen and being lazy (hes very clever) so one would think he'd understand but he doesnt seem to its driving me nuts
