Has anyone else had this problem?

My husband watches our four month old most nights when I go to work. About the time I leave, she starts to cry. Acording to my husband, the rest of the night she is inconsolable and crying hysterically and he has tried everything to calm her down (rocking, singing, cartoons on t.v., feedings, diaper changes, etc.) But the minute I pick her up, she stops crying. My husband is taking this pretty hard and I don't want him to be discouraged. Has anyone else experienced this before and what was the problem, then outcome? All opinions welcomed, even if you are not yet a parent.
