I am concerned about my 10 year old daughter and 6 year old son. Almost every morning I find my daughter in bed with my son. She goes to bed in her own room at night, but sometime during the night gets up and goes into his bed. Should I be concerned about this? I guess i'm also worried because they always want to take a shower together too but I won't let them. I think 10 years old is too old to be showering with her little brother. She never sneaks into her other brother's bed, which is in the same room. Any thoughts on this?
