Ok, not sure how or when this started but my 6 year old son has recently started to get scared of sleeping alone. His brother and him have shared a room for last 4 years with no issues. But now when my oldest goes to his dad's house my youngest doesn't want to sleep alone. I haven't had this experience before so not sure how else to deal with it. I have read some online info. Sometimes he says there is monsters, then next night its because he thinks he might get sick and be by himself (got sick in bed a few months ago but brother was still there) to something another night. Any hints from other moms who have dealt with similar would be great.
