Mommy Until Daddy Comes Home

It's weird, most days my daughter hears my husband come home from work and she gets so excited. Sometimes, I find myself feeling like "Oh, who am I? Chopped liver?". Here it is, I have been playing with her for the past hour or so and just like that, I am ignores like some toy she has outgrown. Then there are moments where my husband comes home and my daughter ignores him. Then I'm kind of bothered by that. I say to myself "Man, I'm tired. Why doesn't she want to go to her father and give me a break?" I guess it's kind of a darned if you do, darned if you don't. I still love playing with my daughter, but things can be a bit complicated. Thoughts?
