Are you a stay at home mom? Does your husband work outside the home? Maybe she is craving attention from him more because he's not always there. It's like...if you eat an apple every day, sooner or later, you're going to want a pear! She sees you every day all day, so when the pear is home (daddy)she is going to take advantage of it. Also, for some reason, girls kind of automatically cling to daddy and boys to mommy. When my son was born, I couldn't so much as look at my daughter without her screaming "papa!!!!" He couldn't walk to the bathroom without her following, screaming "DADDY!!! PAPA!!!" It took a few weeks before she would let me change a diaper, comb her hair, get her dressed, etc... She is still a daddy's girl, but I figure it's normal and I WANT her to have a good relationship with him because I didn't have one with MY father. She will snuggle up in my lap if daddy's not home, so I know she loves me. But if Daddy's home, she only has eyes for him. I know it hurts, but try to be happy that SHE is happy and just enjoy watching them together enjoying each other so much. It's very heartwarming! Sorry I can't help more. It just sounds like a case of "She can't miss you if you're never gone." Maybe if you left her with him for a weekend and went somewhere by yourself for a couple of days, she'd be the same way to daddy that she is to you. It would be "mommy here?"
