What's my name?

When PJ was first learning to talk, I was surprised, for through he said Abba and milk nicely, he didn't seem to have a name for me. At least that was what I thought...

Then I took him on a trip to my parents. While I was taking a nap and my mom was watching him, he was looking at a picture of me holding him that my parents had put up on the fridge. He was eagerly pointing at it waying something that sounded a lot like my first name. That's when we realized he did have a name for me- just not what I was listening for. I had to convince my husband to start calling me "Mommy" though he wasn't thrilled with the idea.

My guess is that this is a first child only phenomenon.
