If you are going by the number on the calendar, my youngest son just reached the 2 month mark last Wednesday. If you are going by the label on the tag, it is a whole different story. I just pulled out the box of clothes marked 6-12 months. In Carter's clothes he is in the 9 month size. At this rate, I just might have to pull out Abe's winter clothes from last year when the time rolls around.
