fairy soup - happy hooligans - outdoor sensory activities for kids. This is also a free activity you could consider mentioning to parents; a trip to the local park and then play at home. Also called a messy mixture, or "perfume making"
Fun area for boys and all those Tonka trucks and John Deere tractors. Backyard Idea, for sure!**- definitely NOT just for boys, my 4 year old daughter would absolutely love this & play in it every day we let her.
