I have 2 grandchildren, 3 & 5 that were here last week…we live in Florida. We have a small side yard in a mobile home park. They started out watering my plants with a detergent bottle, and ended up having a “water party’!
(as they called it) I let them fill a couple of dishpans with water and gave them a couple of detergent bottles and sqeeze bottles, and they had so much fun soaking each other. Later they spent their time painting my porch with buckets of water and paintbrushes.
They love large cardboard boxes, too, to play pretend space ship, house or whatever.
Do you have a library nearby? Ours offer storytime and other playtime activities for toddlers.
Also, our church offers Vacation Bible School, which has a lot of fun activities for toddlers. Not all VBS work with preschoolers, but most I’ve been affiliated with, do.
