My kid adores anything with stickers or art. He is so proud of his art. We put it in the wall and anytime anyone comes over (even repairmen) he will insist they look at his art and he will tell them all about how he made it. I cannot love this enough.
He retains everything too. "Octopus are supposed to have 8 arms, but mine has 5, because I ripped some". My little dude, may you never change.
