Babies born via csection..

Mommy
Doing some research and found that babies born via csection have a higher chance of having colic and/or reflux because they weren't exposed to certain bacteria. But supposedly there's a probiotic for breastfeeding moms that can help, I'm looking into that now. But I found it interesting to know a csection can cause that, also obesity, asthma, and allergies it stated.
