Jello Digging: This one is going to get messy and needs some prep work, but it’s so much fun! Babies and young children are still learning how to be a little human. Everything they touch, smell, hear, and see is something new and exciting. Add some toys like dinosaurs, strings of large beads, cars, or anything else your child can grip into a large container of jello. All of their sensors will be engaged with this little activity, and they’ll get a tasty treat.
