Seems like we don’t play as much during the school year.
A few of our favorites:
Blind man’s bluff with all the lights out
Bottom Wars on the trampoline until everyone gives out
Crack the egg on the trampoline- my chiropractor just loves this one
The Mommy mummy (basically, chase through the house)
Kill you with kindness (chasing my son and tickling him to death)
Colors in the swimming pool
