Did you LO really wear it for all 6 months? K started out slow, even still can wear some of her 0-3 clothes at 6 months, but outgrowing stuff. I'm wondering if her 6-12 months clothes will really last 6 months? When did your LO outgrow 6-12 or have to move up to 9 or 12 months? And how come there are so few brands that carry 9 months clothes?
