My 16 month old is very short, so he struggles to reach the top of the wall to pour the water. No fear, he enjoys pouring water straight onto the wall. I love the fact that the wall is two sided as we packed it up and took it to a play date for kids ranging from 16 months to 12 years. Everyone played with the wall, and it was the center piece of the playdate for much of the time! We purchased an extra set of the accessories, even above and beyond the two packages that came with our box which made it nice because the older kids who understood basic engineering and cause and effect had a blast working with just the shoots! I would absolutely purchase this again!
