Other than the issues already stated here - the other largest answer in my opinion and limited experience is the dual income household and limited maternity leave. I can't imagine trying to pump and hold down a full time job as well as all the other parental duties. Some can certainly pull it off, but with what appears like heroics to me from afar.
