I lied.

Remember when I told you this was the best sound in the whole world?

Well, I lied.
Because, actually, this one is the best sound in the whole world:

You may notice after my little boy looks right into my eyes and says so sweetly 'Mama!' my voice is noticeably absent from the celebration. I was excited, yes! But also stunned, and giddy, and overwhelmed. There is nothing like hearing Mama for the first time from the lips of your baby.
There is just nothing like it.
