When DS1 was a year old we would roll a ball across floor to each other, read books, he has always loved the shapo so playing with that and telling him the shapes hold shape in hole for him to push in etc, wiggles he loves, DS also liked being pushed down hallway on his ride on thomas!
Musical toys he loved and still does xylophone, maracas, drums.

DS1 even now isn't into play doh I get more enjoyment than him, and drawing he still wants to eat pencils etc
