Milk

Sometimes Emily takes longer to finish a bottle because she's so distracted by other things like looking out the window, trying to pull my hair, trying to roll over, trying to sit up or trying to babble and smile instead.  When she gets really distracted the milk starts to dribble all down her chin and bib and I can't help but think of Joey drinking a gallon of milk in ten seconds.

Yes, there's a Friends reference for everything in life :)
