Aaron did some work for a lady that owned a preschool and didn't have enough cash to pay us. So, she paid us in preschool days. Lias went for three of them before we decided to not take him anymore. At first, he was super excited about it but then, said he didn't want to go. Plus, he came home saying things I didn't need my then-2 year old saying!
Yes, our daughter likes to play with trucks and cars. It might be that that's all we have (until her birthday, when she got more "girly" stuff). But, she survived and seems to be better for it...
