Query: frustrating

I bought this toy for my 18 mo old to help with learning shapes and colors. The toy is frustrating for him to use on his own. The pegs do not stay in the foam base and are a little challenging for him to get back in on his own. Any time he tries to pull the pieces off, the whole peg comes out of the base. Okay toy with adult assistance, but definately not what I expectd. Great idea, but not well thought out.
