take turns
I brought one of Ally's slides in the house the other day so she could play with it. She spent a very long time sliding down and sliding one or the other of her care bears down it. She took one from me and said "it's yellow bear's turn" and slid him down then followed behind. I had to clap and Yay for them both. "It's not pink bear's turn, it's yellow bears turn. Wait pink bear" and so on. Then she'd switch and make yellow bear wait. She's really good at taking turns with the toys when she's playing alone.
