How does insurance work with pregnancy etc?

With the deductible & out of pocket maximum & child birth...my deductible is $3100, out of pocket maximum is $5k. When I deliver the baby via csection will she be under my insurance? Or will I get billed per her own out of pocket deductible? UGH. I am driving myself crazy.

How tf do people afford more than one kid on this scam called insurance?
