Guinevere is really weird in clothing sizes. For pajamas, she is in 6-9 months, which would make me think she is tall (except that she is apparently only 10th percentile for height?) but she can still fit into a few of her 0-3 dresses. This dress is a Carter’s 3 month, and while its pretty short, it still fits well around her shoulders and torso. It won’t take much for her to be taller than her mama, so perhaps Tyler will get the tall daughter he was hoping for?
