It's a phase. My 2 year old son has been doing this a lot the past few weeks (he's been sick, and you know how that makes everything worse.) Actually, he's been going back and forth lately, sometimes preferring Dad, so at least we can take turns, but USUALLY he makes it VERY clear that Mom is gold standard, and Dad is an Inferior Substitute Parental Unit (or ISPU). If you can find the humour in it, it makes things more bearable. (Dad looks hurt and says "Hey, I'm a Perfectly Acceptable Parental Unit, too, you know." And of course my son furrows his brow at him, or turns his head away and buries it into my shoulder. You just have to laugh.)
What I do is just ask my husband to make dinner while I hold the baby. (And that's NOT an easy thing to do, letting him make dinner, because this man, bless his heart, had managed to make a kitchen catastrophe out of Jello, which I didn't think was possible.) I know it's tiresome, but you can hold the baby while you have a glass of wine, or *maybe* read something. Think of how short the time is - imagine yourself in 20 years when she's grown up and how fondly you will remember these times.
And just to let you know you're not alone, yesterday my son woke up from a nap and *insisted* on "Daddy snuggles" - Mom would NOT do. Then this morning (right after I left for work - Dad's staying home with him today), he woke up and asked for Mom and whenever Dad came near him, he cried "No! I want MOMMY!" and literally swatted him away.
