Hi! Not sure how much space you have but my school bus slide, playhouse and kitchen got used all day!! Playhouses are big and expensive but a kitchen set is fairly small and encourages so much imaginative play! I got my kitchen for $20 on Kijiji and it looked new so you don't have to spend a lot! I have a tent that I filled with balls, cheap and younger kids love it! Sounds like you have most of the basics already. I wouldn't invest too much more in toys, maybe look for things that encourage imagination or movement instead of a toy that only has one use....does that make sense? I just got a big chalkboard for the wall which I can't wait to get set up!
