I am home after a week in a hotel. It was the first time I'd been away from Daughter for more than five hours. I survived the five days much better than I feared, as did they. In fact, it seems Daughter slept better this week than she has since she was just a few months old. Amazing. I'm trying to believe it didn't have to do with me leaving the house. While I was away, Kansas Dad added back dairy, and she's seemed to handle it fine. He did make sure she had plenty to drink before bedtime (she does love her water) and double layered her pajamas (a onesie underneath her footsie pajamas). I guess she was thirsty and cold.
Let's hope she continues to sleep well now that I'm home.
