The HearthSong® buddy bumper suit is one suit your young one can go all out crazy in. Designed for children ages 6 and up. The translucent blue ball gets kids moving, laughing, bouncing, and bumping, so be sure to buy at least two. Now, for you child-brained adults, this should fit those who are particularly small; size 6 and below should be fine, according to some comments. When done bouncing, this could also make for a good Halloween costume.
