I really wanted to like this. There's so many sensory play aspects to this that I thought my infant son would love. Ultimately, it was too large and hard to hold on to the bumps that protrude from the ball for a small hand. Only recently has my 24 month old been able to pick it up without putting it down immediately. Also, it is nearly impossible to clean. There are plastic pieces, shiny vinyl-esque pieces, and true fabric pieces. My son got the flu at one point (around 10-12 mos) and I tried to clean it, but ended up wiping it down hard with a chemical-laden sanitizing wipe and then hoping for the best. There are far better sensory development toys out there that can be properly cleaned.
