My little niece is laying down in bed right now and she's holding a picture of her mom and dad and she's crying. She cried " mommy ". She really misses her mom. Her mom and dad are in Nashville TN and we live in Ohio. Her dad works there and her mom had to go with him. She's getting ready to go to sleep but she always sleeps with her parents and she can't sleep without her mommy. How can I comfort her ? How can I make her stop crying ? she's 5.
