Are my kids trying to tell me its too cold in our house?

Kevin let me sleep in a bit this morning and when I walked out and saw Hailey eating breakfast with her winter hat on I thought it was pretty darn cute! Kevin said Hailey put her arms around herself and said, "cold" so he got them each a blanket to wrap around themselves. Then Hailey pointed to her head and said she wanted a hat too. I keep our house at 70 at night to keep Scott's asthma down (especially since he's in the basement) and then 68 during the day. Is that so bad? My kids think so!
