I think I may have figured out what the deal is with babies and all their crying, they are itchy. Think about it, have you ever had an itch someplace that you couldn't get too. Maybe you were carrying something that you couldn't put down, or performing at a piano recital, maybe you were kidnapped by keebler elves and they tied you to a chair while an itch on your forehead drove you nuts. It can be darn near unbearable!
Now think about babies, they cry when they have a need that they can't meet themselves. Many times you can pinpoint the problem; they are hungry or tired or poopy. Sometimes no matter what you try, they just keep bawling and bawling. I've tested my theory on Dahlia a few times, but it only seems to make things worse. which doesn't really surprise me. Having someone else try to scratch your itch never seems to hit the spot. So until she's older and can scratch her own itches, we'll just have to keep watching her suffer.
