Im pleaed to read that no one hsa put you off as yet - thats a good sign.
Im a sucessful HVBAC mother, basically means home vaginal birth after caesarean - which is damn risky aparently.
I enjoyed every second of my home birth and i too obviously had the section child there too.
At the time he was 19 months old - but soon went to bed as i laboured day and evening then gave birth early hours.
I am pregnant again and of corse planning another home birth, and if im pushin through the day the children will be up stairs in their bedroom out of the way.
As for mess - the midwifes lay down plenty of pads square ones and believe me i gushed with the birth and guess what - not even a spot on the sofa !!
And as for the only 2 small canisters, they allocate each home birth 2 canisters but if your near to running out on the 2nd they bring another mw out with more - i used 2 and a bit canisters

but my first canister had only a quater in it.
I wish you the very best of luck - if u need to talk further give us a PM
