There have been some great responses in "nursing and colic" thread.

I just want to add another question that has been helpful to me in my
practice.
I also ask mom if she smokes tobacco or if baby is exposed to second hand
smoke (aka ETS or environmental tobacco smoke). Nicotine (in tobacco) is also
a stimulant and makes some babies more irritable.

Caffeine (and theobromine) from Coffee, sodas, chocolate and teas seem to also
be another source of "colic."

However despite all sorts of manuevers, changing diet, mechanics of
breastfeeding,  quite a few of the babies in my practice are still "colicy."
I'm not so convinced that  all colic is necessarily "curable"- perhaps it is
also a part of a developmental stage?

The biggest things I stress are "wear your baby" (sling, snuggli or more
traditional wrap), use white noise (the static noise from washer-dryers,
dishwashers, radios and tvs)  and remember that colic will not last forever (a
mantra I repeated over and over in my mind during my own son's first few
months of life).
