Jas was 8lb 3oz and went home in 00000 as she was really short. She was in this size for about a week to 10 days then in 0000, then in 000 by three months. For this one, I have packed 00000 to come home in, but a couple of different kinds of outfits - one all in one and one pants and t-shirt with no feet in case he is taller.
