Activities for a 3 yr old autism boy

[Tam86]

Hi
I have a 3 yr old boy in my room that has autism he doesn’t sit for group activities and likes to do things on his own he really likes climbing over the balancing beams and just walks around, sometimes he will sit and look at books. The biggest thing he does is eats his nappy. His mum has done everything to stop him getting to his nappy and nothing stops him.
What I am trying to ask is, is there a way we can stop him from eating his nappy and putting things in his mouth? And what activities can I get him involved in?
Thanks
