"1. im not scared of hospitals - being a nurse the equipment or the monitoring is not an issue for me."
Your midwife will have equipment with her for a homebirth. She will monitor your baby's heart beat with a sonicaid. Giving birth is a natural event rather than a medical proceedure. Its much nicer being monitored by a human being than a machine.
"2. im i very private person and hate the idea of the neighbours knowing. or MIL "popping in"
A homebirth is an intensely private affair. You do not have strange staff you don't know popping in and out. You are in your own space.
"3. we are a good 30 mins from the nearest hospital - is it really safe? (previous birth was normal with G & A)"
An ambulance driver can get you to a hospital surprisingly fast.
"4. im worried about my ds seeing me in labour but would it be right to ask someone else to have him if i have a home birth?"
Of course it is. You will need someone to look after your ds whereever you give birth. If there was an emergency that required transfer to hospital you don't want to be faffing about finding a baby sitter.
"im just not the earth mother type at all but the idea of being in my own surroundings and away from hospital bugs really does appeal.
any thoughts / experience good or bad is much appreciated."
A homebirth is not for everyone. If you think you would like a homebirth I suggest you book one early in pregnancy. Its very easy to change your mind from a homebirth to a hospital birth, but much harder the other way round.
