This has taken over my children's lives

The boys were introduced to beyblades right after Christmas, but we held off on buying them until the end of January, and the boys are obsessed!! Will talks about beyblades all the time! It almost seems like he is annoyed when you want to talk to him about something other than beyblades. Even James plays with them while Will is at school. I played beyblades with James for about 1 1/2 hours yesterday. We only stopped because the baby needed a nap. I am amazed how a spinning top can fascinate them.
