My DD is 17lb, 6.5oz and she can still wear the 3-6 month stuff. It says "up to 18lbs" on the tag. I put her in 6-9 month stuff to have a bit more room sometimes too. I was just wondering if anyone else has found that they DON"T have to go up a size w/ cding? I thought that the rule was to go up a size to compensate for the dipeWe use mostly pockets and CPFs, and don't have a problem with many clothes yet. That might change when we get to wearing jeans this winter. What is your experience with clothing sizes?
