I know for a fact that neither of my boys ever wore more than a single piece of clothing more than a single season. Kaitlyn doesn’t appear interested in growing at a rapid pace and is fine in most of the clothes she wore last spring.
Kaitlyn at 10 months. (9 month jeans and 12 month top)
Kaitlyn at 13 months. (same 9 month jeans and 12 month top – bow is slightly bigger)
