ds (age 7 almost with sensory issues and imo asd traits) is confusing me very much in these last 24 hours, last night he was mid watching his dr who and i had to tell him it would need to go off before it was finished so ds2 could get to bed i expected HUGE tantrums over this as would always have happened but he said 'ok, can i watch it tomorrow' and that was it! i had to pick my jaw off the floor!. Today - he ALWAYS has his snack at 10am if he dosnt he gets very very upset is is also food obsessed never full even picks litter up off floor so i went and brought it through to him and ds said 'im not hungry maybe later' 
who is this child and where is my ds?? Hes now sitting watching dr who rocking back and forward but with no usual noises, he is however pulling a strange face, i asked what are you doing and he said 'biting the inside of my lips' but didnt know why, but still no noises! also last night he was eating dinner and ds always eats quickly and overstuffs his mouth to the point of choking but last night he ate so slowly like a mouse and ive noticed has been doing it with biscuits etc recently too taking like 30 mins to eat one.
Was just speaking to dh and he said its like someones flicked on his 'normal' switch not the best way to put it but i know what he means. Ds has still acted oddly this morning, pulling wide strange faces, jumping on me, lying down beside ds2 (age 1) and acting like him wanting me to rub his tummy etc but things like the above make me doubt if i have all my concerns all wrong, im so tired of doubting myself and not knowing if im a concerned mum fighting for her son or a paranoid one who needs to step back :(
can anyone relate to this at all?
