Only time I "plan" clothes based on future LOs would be at Christmas time...can't have horribly clashing colors on my boys that don't go with the Christmas paper line I've already picked out!!!
Otherwise I did have a clothing related YMBASI moment last summer when I put on a new pair of capris and decided that while I liked the pants I couldn't wait for something to happen to them because I fell in love with the buttons and wanted to use them on a LO!!!
And I too want to go to DisneyWorld so I can use the too-many tons of Disney embellies and papers I bought to do some old Disney phots...I think I have more supplies than photos!!! I'll just save them and hope we can go there when my boys are a little bit older.
