I am struggling to think of interesting activities to do with my toddler as he still is wanting to put everything in his mouth. Drawing is no good as he chews the crayons, pens. Same with play dough. Gluing was no good either as he just wanted to chew on the glue.
We do play with sand as he stopped eating this. We also read books and I just put them away before he has time to chew them. We also do blocks, cars etc as it doesn't matter so much if he chews these.
