You should have seen it! Nathan (our 18 month old) can jump! For Christmas, I bought the boys some little glow in the dark planets that stick to the wall. I placed them just below the ceiling in the boy’s bedroom. Nathan has had his eye on them for several days now. Tonight he went for it! He got right under those planets, he wound up his arms, and he jumped as high as he could. I’d say his vertical leap is a good 1 centimeter. I’m thinking of getting him a basketball.
