Winter pajamas in August?

Can you believe Carter is in winter pjs already in August? It was nearly 90 out today. We keep our house relatively warm at night, too, and yet, he is always cold when he sleeps. We have found that if we keep him dressed warmer, he sleeps much better. He doesn't keep a blanket on, so we have resorted to winter pjs in August - go figure! Makes me warm just looking at him!!!!! I guess you do what it takes to sleep! :)
