Why is it ?

Every time Marcus wakes up at night crying or wakes up very early in the morning he wants his Mommy. If Daddy tries to calm him down, he screams and screams. This is really weird because he LOVES HIS DADDY, and wants to be with him all the time. But at night he wants his Mommy. So last night, the one night that Aaron is gone, guess what???? He wants his DADDY!!!!!! I know it was just one night this time, but Aaron- we miss you. Come home soon.
