Our DD is due in October and we're hoping to get as much secondary wear out of DS old clothes as possible. They aren't especially "boyish", quite neutral/ unisex. But at what age would you stop feeling ok using hand-me-downs and want your younger child to have they're own clothes? Not that she'll never have anything new to begin with, I'm sure we'll be drowning in cutesy pink newborn baby clothes from family and friends, but I don't want to buy a whole new wardrobe when all DS old stuff is perfectly fine and she'll grow out of it in 2 seconds anyway!
