I'm still wondering who sets the sizes for infant gear. Grace is coming up on 4 months and is already into her 6-9 month clothes. And some of those don't fit so well either...
We’ve had a similar problem. Maybe they size by international averages, or even by the size of kids in China or Guatemala, since that’s where they’re making the clothes.
It sounds like Grace is flourishing! Give the Mom my Raucous Round of Applause (and a Guinness, if she likes).
