Watch the Bubble Guppies video, talk about it with your child, then try to incorporate the activities to build awareness that it's more fun when everyone plays.
In this Bubble Guppies video, three little fish are playing a fun game and don't want to let a fourth little fish play with them. But excluding someone from a game or activity can cause hurt feelings. It's more fun for all when everyone is included.
You can help your child understand that excluding someone from playing can make another child feel unwelcome and sad. Helping children develop empathy--understanding how their actions affect another person's feeling--is an important lesson parents can teach their kids.
