DS' room is kept at around 65 degrees throughout the time. We used to put him in a long-sleeve onesie, fleece footed PJs, then a fleece armless sleep sack over top. He recently had a growth spurt and outgrew most of his onesies and fleece PJs. Today when I went to get new ones, I couldn't find onesies for 18 - 24 months and I was told that fleece footed PJs are no longer being carried this late into the winter season. I went to 3 different stores. Finally, I bought a few cotton footed PJs but am worried that DS will get cold at night. I don't really want to turn the temperature up for the entire house; and am worried that a little heater in his room would make it too dry (DS has eczema). He won't keep a blanket on.
