Marley will be 7 months old tomorrow! Here is a photo of Lily the day before she was 7 mos old. Lily was much bigger than Marley is now. Lily was wearing 6-12 mo and 9 month clothing and Marley is still wearing 3-6 mo clothing and some 0-3 pants. Just goes to show every child is different. I'm going to get out a pair of the pants and shirt that Lily wore at 7 months and see how big it is on Marley.
