This swimsuit is so cute! I am leaving a review to thank other moms for leaving their reviews. Based on a review from a mom who has a huge 4-5 month old baby, considering her baby's weight and height and the size she ordered, I bought the 18-24 month size. My little girl is 5 months old, weighs about 25 pounds and is 27.5 inches long and this size fits her almost perfectly. There is little, not much, room to grow. I may see heavy use of this swimsuit for another month or two. It's a little depressing, but it's so cute that if she outgrows this one, I'll probably buy another one. The picture I've attached shows the ruffle swimsuit for 18-24 months and Carter's romper for 6-9 months. Hope that helps!
