My DS is 17mo but think they still like similar things. Things that involve moving and independence.

We have a few different things we do together. We might throw balls to each other, stack cups, play with shape sorter, read books, dance to playschool together, build with his blocks. We also occasionally play chasey around the house or peek a boo.

He loves going outside, so we do that whenever the weather is nice. Out there he has a swing, a cart, garden tools, trucks, mower and broom. He also likes to walk around and explore. And talk/feed our birds, mainly our galah.

I'm up for more ideas though.

I came up with something he liked doing whilst in the bath. I got a bucket of water and added a few drops of food colour. Then tipped it through his bath toys. He loved it.
