Would it be too horribly cruel to do CC at 6 mo? My dd's sleep has totally degenerated since she was the perfect sleeper at 3 mos. I can't let it go on like this as she shares a room with my oldest dd, and every time she wakes up, she wakes #1 up. She woke up every 45 minutes last night, up until 12AM when I took both her and her big sister into bed with me (Much to the annoyance of DH). Help me please, I am desperate. I need to do something! Oh, on cue--there she is crying again!
