Since this is a building toy, I wanted to point out an observation made years ago when I had a temp job demonstrating a different building toy. Little girls under age 5 are absolutely amazing! As long as you can keep the parents away from them, little girls are way better at building toys than boys the same age IMHO. But you must keep the parents from interfereing! For some reason parents think that if they can't do something then their little girl can't either (parents don't do this to little. boys IMHO). The thing is that girls seem to listen to their parents. I saw this over and over again. We had a play area set up and we sold the toy by getting the kids to build something, their parents would see them having fun and buy the toy. Except with little girls, the girls would jump in start building and doing amazingly well but instead of noticing, the parent would try the toy, have trouble and announce (without looking at what their girl had already built) "this is hard, you can't do this." "The little girl would look at her house (or whatever) and say "I can't?" and immediately stop building. I could never get the parents to look at what their girl had built, so I learned that if Ii wanted to sell to parents of little girls, it was absolutely necessary to keep the parents away from the girl until she was finished building and had something completed to show. The sadest thing is that this only applies to girls under age 5. Girls under age 5 were fantastic at building, age 5 and above, they were terrible or just didn't try. This led me to conclude that by age 5 little girls have properly socialized ( or as I put it--ruined) by their parents and perhaps society. So my pled for parents, esp parents of little girls--please stay out of your kids way. Please don't tell them something is hard--let them learn and discover for themselves. Most important open your eyes and look at what your kids can do! I am telling you, little girls between the ages of 2 and 5 are amazing at building things--let them do it. There is no rational reason for a two year old girl to be better at building than a five year old girl--yet I observed it over and over again. I have no comment on this particular toy, I am just saying that little girls are fantastic builders in general.
