Sour things are slightly addictive to kids. Once they take one bite, it's hard not to keep going back for more. And these squares push the level of tanginess thanks to the combo of lemonade, orange-flavored JELL-O gelatin, and mandarin oranges. Think of them as a tart party for your little one's mouth.

Pour the JELL-O gelatin and lemonade into a small saucepan and heat until dissolved.
Invite your child to chop the mandarin oranges, and layer them in the base of an 8x8-inch baking dish. Cover with the JELL-O gelatin.
Set in the fridge for 3 hours or overnight. Cut into squares and enjoy!
