Shelby is, as of yesterday, four months old. She celebrated her "birthday" by breaking out in a side-splitting full-bodied giggle that had us all nearly in tears. I'm not really sure what makes babies laugh (perhaps just seeing her big sister act like a total goof?), but it's well worth the wait, and it's one of the milestones we look forward to the most! There is just nothing quite like a baby-laugh. Well....I take that back.....there is something oddly satisfying about catching Daddy behaving like a raving lunatic in the name of trying to get said laugh...observe (you may have to turn up the volume a bit to hear Pete's babbling):And "they" say that moms lose brain cells with each pregnancy?
