Those with more than one child: do you go through phases where you secretly favor one or are temporarily more deeply in love with one child over another?

Maybe it fluctuates with our children's needs, but right now I'm head over heels for M. She and I are having a little love affair with each other this week. I've felt the same way about Lala many times and had the similar feelings about her about a week or two ago.

Do you ever experience this? Is it wrong or embarrassing to admit this?
