I've just bought from Big W a Smash insulated lunch box for DD and a set of Sistema containers. We have forty-five thousand Tupperware containers but my DD can't open them - this feedback came from the kinder teachers. She can handle Sistema (I think!) so I grabbed some of them.

The Smash lunch box has a zipper compartment on the outside so I bought a flat Decor ice brick that will slide in.

Drink bottle I think I will just stick with the plastic ones we've been using this year - they've lasted pretty well and DD knows how to refill it. They are just the cheap ones from Big W, Barbie Thomas etc.
