Query: This will actually keep them interested.

This was bought by grandpa for my son's 4th birthday. He loves this. He has had it for 1 week and I can not get over what he has learned so far. He'll say "Mom, I am working on my shapes" or "I am working on opposites". Before this, I would try and sit and work with him on these things and he didn't care. Now he is telling me all about them. The Leapster is absolutely amazing. What a wonderful idea!!! This is the by far the best learning system that keeps the interest of the little ones.
