Addison wore it around the house at the very beginning when the house was a little cool. Sometimes she did, sometimes she didn't. It's not like we stressed if it was off for a few hours or something. She doesn't now, but of course when we go outside she wears one because it's freezing.
We also had to turn the heat up in the house after we had her. I like it cool. DH likes it much warmer than me though, so he was probably happy
