I'm a postpartum doula who works with new moms, and I also work with some online and IRL moms' groups as a "resident expert" of sorts.
I'm torn about gas - much of my reading, research, and training says that gas problems are not that common in babies, that they used to be because of crappy formula. But, most of the new moms I know blame gas for their babies' fussiness and crying, even when gas treatments don't work. (I'm not talking about needing a burp after a feed, but a chronic, ongoing, "My baby is crying so it must be gas/GI related").
Honestly, I have never seen a baby in my practice with what I would say is unequivocally a gas problem, but the babies I spend a lot of time with are a small portion of the moms I interact with overall.
What has your research and experience told you about gas? Breastfeeding or bottle - both moms seem to blame it equally. Thanks mamas!! I know my MDC smarty-pants mamas will have some brilliant insights :)
