I think that's typical. I know there are lot of moms who pack away some of there toys to rotate. This then allows the kids to not be overwhelmed by the selection - since they play only with a few things anyways - and it's like they have new toys when they rotate in the packed away toys and put away the others for awhile. My son (8) definitely goes through phases of what are the key things he plays with - while other stuff sits unused. =-)
