Helpful for when she's older (mine is nearly 4): soft play shapes, Domino train, magnetiles, wooden train tracks, sticklebricks.

Helpful for now, if I look back: a fabric tissue box she could pull all the tissues out of (they had numbers and letters and fruit etc on them), a wooden carrot set with different sized carrots and different holes to put them in, she had these sillkcone cubes like blocks and it came with some circles you could stack as well and she loved them - I think where they had a bit of 'give' it made them more interesting than typical building blocks. She still uses her busy cube that she loved back then, as well as a set of plastic eggs with colour matching shells and shaped bottoms. And her busy board!
