Hi,
for DS1 I had my DH and a friend (she was there to support DH as he is also very squimish)
DS2 just my DH
DS3 DH and an Independant Midwife

My first two labors resulted in c-section and my third was a VBAC.
I'd also suggest either a Doula or and Independant Midwife. I chose an IM over a doula as they only cost a little bit more and are qualified to give medical advice if needed.
