Newborns like to keep their legs all folded up resembling frogs. That made this Gymboree Playtime Frog romper pretty fitting. It's preemie size and I bought it for around 50¢ at a garage sale this summer. Oddly, I have no newborn short sleeved bodysuits so he's wearing a Carter's kimono top underneath. When Tillie saw him this morning she said, "Ah, Teddy! He cute!"
He was 7lbs 6oz and 20" long when he was born, so newborn clothes should fit him no problem. They're ridiculously huge on him though. I tried a Carter's preemie outfit on him yesterday and it would have been great width-wise, but was way too short. I have to give a shout out to the Zutano Itzy Bitzy outfit he was wearing yesterday. The fit was wonderful. I highly recommend them in the newborn size if you have babies that are around 7lbs. Although, I might stay away from the one-piece outfits if your babies are tall. I think Teddy would be too tall for a footed newborn one-piece from them. Also, Amazon typically has good prices on that brand.
