We too used onesies on both furgirls after surgery. The Gerber Brand ones fit smaller than the store brand...Milli weighs just 4 lbs, so the Gerber brand 0-3 month fit her pretty well, and the store brand kind in 0-3 fit Emma well at 5 lbs. when she had her surgery, and they still fit her at 6.5 lbs.        |
