Howdy, my dd is a great little sleeper. She goes down for naps and bedtime with no problem. She also has never had a problem staying with grandma or my babysitter. Anyway, this last week she has woke up in the middle of the night crying. I alway go check and can't find anything wrong. She never seems to be awake. I rock her a little and put her back to bed. Sometimes she goes right back to sleep and other times she wakes back up in half hour. I'm not sure what is going on. She has done this 3 times now. If she had ever had any issues with sleeping or seperation I might attribute it to that, but she never has. Any ideas?
