Hey Becky
DS is 19 months now but his toys haven't changed much tbh (other than normal rotation that is).
Wooden blocks for building, looking at pictures and letters
Mega blocks for building, colours
cars tractors, trains and trucks and his little people garage
kitchen has been a hit here for a good while. pots and pans, toy food, shopping basket, tea set etc.
balloons (sometimes helium, sometimes regular)
flash cards he loves because it's like a book to look at pictures but he gets to fill and dump them too. We also play a fetching game with them.
Arts and crafts stuff (ink pads and stamps, wax crayons, felt tips, foam stickers)
tub of plastic animals
tub of cotton reels (for stacking, rolling, counting and threading)
ride on
stacks of books on rotation
musical instruments are never rotated out of access (we have quite a few things that aren't rotated out now)
He also really loves climbing and throwing himself on a big bean bag and playing tig and balance games and rough housing with me.
