These higher end stuff that you put your kids in, do you find they last?
I find that they generally last longer. The empircal test for this is to observe which items make it to my nephew, and the more expensive stuff is definitely more durable. We don't treat one set of clothes preferentially to the others, so he barrels right into the muck in his Bonpoint.
The pleasure of getting the higher quality stuff is magnified by the knowledge it will tend to be used twice, which seems much less wasteful than it otherwise would be for swiftly growing kids.
