I don't know if it's just our kids, but all three have loved to climb inside that ottoman.
We call him "Helper Baby Plum" around the house, and he loves it. He loves that he's known as the helper of the family, and will almost always help us when we ask. I can't remember him fussing about it, either.
He's also adopted a nice new habit of holding the storm door for me when we're trying to get out of the house in the morning. It's very nice.
