A mini party or a picnic. You could do some, all or none of the following:-

Make decorations for the house or have a picnic
Make party or picnic food together
Both dress up
Dance and sing together
Take photos
Or just go out somewhere special and eat out

Baking - and taking some of it home for mummy and daddy.

The seaside, the zoo, an icecream parlour.
It depends on the weather, what she's allowed to eat, if she's interested in animals, I suppose.

The seaside would be my choice.
