Thanks ladies. Erica was 19 1/2 inches when born. At her one week appt she was 20 1/2 inches. I'm not sure how long she is now, but shes gotten longer. I'm really surprised she is still in them, but its ok, shes got a lot of cute newborn clothes. I've started to put 0-3 onesies on her if I need to do her laundry and dont have any clean newborn ones. (She spits up a LOT) They are ok, just still kinda big. We bought a couple more newborn outfits so shes got more now.
(With my luck, she will outgrow them tomorrow now LOL)
