LO started wearing pjs this weekend. No more zip up sleepers for this guy. I bought some Carter's 2T pjs at Target yesterday. They aren't the super tight kind. The pairs I picked up months ago were light and roomy. I noticed that the weight size said up to 31 lbs. LO's currently at 29 lbs. Should I return the 2Ts for 3Ts? Will the 2Ts last us through the rest of the summer into fall? What's the fit like for your LO?
