That is the goofy part, while actually giving birth at home is not illegal direct entry midwifery is illegal in Iowa and yes the midwives who deliver babies at home are breaking the law,it is considered practicing medicine without a license and it is a felony. These midwives risk prosecution when there are complications that is why you have to be very careful when choosing a midwife in Iowa. I know of one midwife who will call an ambulance and leave you alone to deal with the EMT's if there is a problem.
Homebirth is highly frowned upon by CPS, by the way. I had a friend who had problems because of it and it can sometimes be difficult to obtain a birth certificate. Depending on where you are in Iowa, each individual county is different, with the smaller ones usually giving you the most trouble.
I live in Mount Vernon, which is in the CR-IA City Corridor.
I have a question for you, does knowing the legality of the situation change your mind about having a homebirth in Iowa?
