Babies are an excellent treatment for squicks, albeit up to a point -- there are things I don't mind from a baby that I mind from an adult. Like being gummed upon. Or peed upon. Or...

This reminds me of a funny story from when E was toddling. I was at a party with a bunch of parents and children, and one of the women I was sitting beside had her kid toddle up, wipe face on her shoulder, and toddle off. I joked that she was definitely anointed as a mom, and then E toddled up, wiped her face on my arm, and toddled off. I felt both slimed and loved. :)
