The GP and midwife you are looking at are both very experienced, with Peter Lucas who
has been a general practitioner for 35 years...and has attended in the order of 5000 births as a specifically trained General Practitioner. Peter has wide experience with hospital deliveries and planned Home Birth.
and Jan Ireland
who has been involved in hospital births, birth centre establishment and home births for 30 plus years.
I don't think the experience of either professional is in dispute. I think it is really important how comfortable you are with your health care providers and how they work with you.
