Babies cry - it's a fact of life. They cry when they're hungry, when they're tired, when their nappies are wet or dirty, when their tummies are upset, when they're too hot or too cold or just plain bored. They cry morning, noon, and night. Eventually, their exhausted parents start to "learn" what those different types of crying mean, and start to figure out how to soothe them - and, blessedly, stop the endless crying.
But some babies don't stop crying - at least, not very easily. They may cry inconsolably for hours at a time, and nothing that their parents do - or don't do - seems to work. All babies cry, but for colicky babies, crying is extreme and uncontrollable. And for the parent of a colicky baby, those crying jags can seem endless - and can feel drive parents to feeling like they're on the edge of losing their minds.
