My 8mo old has quite the cold with stuffy right now, and I want to make sure she's nice and cozy tonight in her crib. The temp is dropping into the 40s tonight and her room is very drafty. We stopped using sleep sacs not long after she became mobile because she didn't like being confined, so I usually just put 1 or 2 small, lightweight blankets on her wearing her footed pjs. I'm afraid that won't be enough to keep her warm tonight, and if I change her little blankets to something warmer, it will be too much. Ugh, I worry about whether she's warm enough or not, or too warm every night regardless of the weather tbh... advice?
