I have found this site with
Onesie Extenders.
V has a closet full of clothes that I'm sure she is outgrowing by the minute. However, I doubt she's getting much "fatter" as much as she is getting longer. I think these will come in very handy!
I haven't been able to find any of these in my usual stores (read Target, WalMart, JC Penney or Dillards).
Maybe I'm not the only one who could use this info.
If you have any experience with these extenders, please let me know how well they work.
