You can mix or match this list. With some of these ideas, a quick trip to the dollar store will net you plenty of egg fillers. Or, you can use the opportunity to clean out your supply of small items in your junk drawer.
Money: This is an easy go-to idea. You can vary the coins and bills you put into the eggs and make it a real adventure and surprise. Children can then practice counting and totaling the money.
Fun coupons: Make redeemable coupons your kids can use to get extra screen time, a day off from chores and other rewards.
Confetti: This is kind of the booby prize, and might be fun to include for older kids.
