My DH delivered DD and he loved it, still talks about it 18 months later!

It was a spur of the moment thing. My OB asked DH towards the end of my labour if he wanted to deliver his baby and DH jumped at the chance. OB was there when DD's head came out to unravel the cord (it was wrapped round her neck) and then he stepped aside and let DH catch her. It was fantastic seeing DH hold her up to me!

I guess it could be an issue if your partner is squemish with blood/fluids though. Last thing you need is your partner fainting lol!
