Nighttime outfit and weather

Sa

What is the temp where you are and what is ur little one wearing to bed? This winter we have been doing fleece pjs and he has been fine (our house is set at 71 and it's like 20 degrees right now) but we are having a cold gust coming with windchill -20 and -9 degrees during the day for the next week. Idk what temp at night. Should I put two fleece pjs?! Lol I can give him a blanket but he always kicks it off. We have outgrow the sleepsacks we used to use
