Sharing with a 4 year old and a 1 year old

This is what happens when 2 kids want to play with the same toy while trying to be nice to each other:

Gavin decides to read a book in Kailee's toy pack-n-play (toy crib)

Kailee decides she also wants in the toy pack-n-play

Kailee decides this is not the ideal situation and wants Gavin out

She can't resist the opportunity to say "teese" for the camera

"Out!  Out!  Mama Up!"
