A bit excessive. Yes.
I spent yesterday and today doing tiny baby laundry. I went through our 0-3 months onesies and sleepers. After weeding it down quite a bit, since they wouldn't all fit into the drawer... 28 onesies and 18 sleepers.
I'll be honest, my children are not exactly in need of clothing. Unless it's Girl's size 10 white sandals for church... then I need 2 pair.
