4 year old very emotional and hitting mum

[Rainbow19900]

Hi my4 year old has started hitting me /scratching my face when I tell him off

we've tried time out on bottom step but he just gets up

we've tried to say " No granny's house " but he repeats it back to us " No granny house for you " and he seems very emotional always on edge of tears

He is on autism pathway but paediatrician doctor doesn't think he has it as he makes eye contact

If he's being assessed for ASD, you might be better asking for some tips in the Special Needs section as often regular discipline won't work with DC with ASD
