Moon sand it comes in a pack from toys r us and is modeling sand for around $25, we had it given as a gift and it's one of the most used toys and wont leave a mess if walked into the carpet like playdough does!(speaking from personal experience, lol)

Fake food also from toys r us, they come in a variety of packs and are used all the time with the kitchen and tea set here!

My Niece (19months) loves her, Dolls pram, tea set and her little table and chair set, she's always playing on it!

Hope this helps,
