Time-out bottles. Fill a bottle with 3/4 water, one bottle of glitter glue, & ultra fine glitter. Then send this bottle with your child to timeout and they can watch it settle to calm them. Once the glitter is settled their time is up!
Painting with water - one of our favourite summer activities! Provide a variety of brushes and spray bottles. Provide each child with a bucket and let them refill it on their own from a large pail of water.
