How much is too much?

I was thinking about this while looking over the holiday sewing thread. My kid's closet is bursting with party dresses. I feel semi-guilty about the size of my stash, so I have been trying to make some inroads, and since I buy small cuts, it limits what I can sew. As a result, she has had a new dress for: Easter, Valentine's, the school's holiday recital, plus many non-occasions (I saw an adult dress in London and wanted to copy a technique, or found a fabric that matched a pair of shoes she has, or wanted to try a new beading style or dye pattern...). Is there a point at which it's just too much? I've been getting hints from relatives that they'd like a spot in the hand-me-down stream (though a special friend still gets first pick) so it's not that things will really ultimately go to waste. Or is it ok that this is a creative outlet for me at a time when I am putting my career on the back burner while I prioritize a more child-centric way of living? I know there's not a right or wrong answer, but I'm curious to know whether other folks have thought about this, and where you've landed.
