My DD1 is totally into the space thing too at the moment! You've seen our rocket ship and the helmet with bubble wrap, she is so cute riding around in it and pretends she can't breathe until she gets her helmet on lol.

Can you star gaze where you are by letting her say up a tiny bit later? We always check out the moon each night and its different shapes.

Ooo just had a good idea for something I will do with DD1 too... make a telescope then make discs to rotate through the front lens with black paper and glitter to make different space scenes, add planets and things too. Glitter is popular here so DD1 will love making space scenes! Flicking paint with toothbrushes works well for this kind of thing too and is pretty fun although messy haha.

Could also do craft activities around making constellations and things, like dot to dots.
