Toddler Sumo Wrestling
Have each toddler wear a size 4-6 t-shirt. Then stuff a throw/toddler pillow inside the shirt on the front side. Let them bounce into each other, safely, or against some other pillows leaned up against a couch. You can even put a big bed pillow inside a big t-shirt you are wearing and ask the toddlers to come give you a hug! Then let them try to hug each other. Tons of FUN!
