Nolan loves to jump in his bed. But when I take the mattress out to change it he LOVES jumping on his bed. First I lean it up against the crib and remove the sheets. Then he hides behind it waiting for me to 'boo' him.
Then he pushes it so it's flat and jumps on it. Jumps like a monkey.
Jumps like a frog. Jumps up in the air and lands on his knees. At any rate, he loves jumping on his bed.
