Happy birthday Cupcake!
I agree with the previous answers. If you're nursing, watch for foods that make YOU gassy and avoid them if you can. (Though I don't want new moms to drive themselves CRAZY thinking, Okay, What did I eat two hours ago that's now upsetting Cupcake's stomach?) Mylicon is a good option. Gripe water works well, too. Chamomile tea has been shown to be safe and effective in all kinds of gastrointestinal complaints in newborns from gas to reflux to constipation, if you want to go a natural route. Just steep a cup of tea like you would for yourself. Cool it. (Duh.) Add a little breast milk or formula if desired and feed Cupcake an ounce or two in her bottle.
Good luck.
p.s. I'm also a pediatrician in addition to being a mom. BTW, I a two-month old patient of mine came into the office the other day wearing a T-shirt that read "Cupcake Seeks Stud Muffin."
