The weather is getting pretty cold. We usually keep our thermostat in LO's room set to 75F (when it gets very cold, it is really about 72F in his room even the thermostat says 75F). I'd put a cotton undershirt on LO, and a one-piece footed fleece pajamas on him. Then I put a fleece sleep sack on him. He is 21 months.

What about you? How old is your LO, what is your thermostat setting and what does your LO wear to sleep?
