For my first I had epidural and it was brilliant. For the second I had nothing but a TENS machine (worth looking into). However, I had a quick labour and Im sure if it went too long I wouldve called for the epidural again. I think there's risk with everything, there's risk in childbirth with no drugs as well.
Do your research and then be open to whatever happens. I wanted no drugs, but I was open to whatever may have come my way.
Also they say it takes a while to get the drugs out of bubs system, but my labour was so fast, I think it took her days to recover from that anyway! xoxo
