When our second daughter was born it was the middle of winter and I think this affected her with some lifelong habits. Maybe it was the fact that she had to be bundled up in layers of blankets when she first came home but she has always slept more comfortably under a pile of them. It could be the middle of summer and I would go into her room and find her bundled up in a cocoon no matter how hot it was. Now that she is an adult and married, our son-in-law is constantly joking with her about her sleeping habits. He also sometimes complains about how high their energy bills are because she keeps the air conditioner turned down so much. She says that she loves to have the bedroom freezing cold so that she can still put on a pile of blankets and feel the weight of them while she is sleeping. We suggested installing a separate HVAC unit in their bedroom so that they didn’t have to keep the entire house that cold just to make her comfortable. This would not only help with the energy bills but it would give our son-in-law the option of sleeping in a separate room if he was too cold. We even suggested that they could have a mini split HVAC unit installed on the wall and it wouldn’t even take up added space. At this point I think he is going to look into just about everything because he wants to make our daughter happy but also save money at the same time.
