How many layers do you put LO in for bedtime in the winter? We've been putting DD in a footed sleeper (sometimes thin, sometimes a heavy one) and a fleece sleep sack. I just wonder if shes warm enough. She went down over an hour ago and just woke up fussing and almost grunting-I know she's not hungry so I wonder if shes warm enough since its so cold outside tonight. Her room is a little cool and we have the humidifier in there which makes it cooler as well. Thoughts?
