Hi Brunette, I'm planning to use TENS too. I've hired and had some training from the physio dept at the hospital.

My plan is to get it on early, utilise with breathing/relaxation techniques, and if it doesn't cover me for transition then I'm thinking I'll try hot shower and possibly gas at that point - unfortunately you can't use TENS in the shower so it'll have to come off then. But if it works for transition too I'll be pretty pleased. The MamaTENS unit I hired has a "booster" button that ramps up the intensity for during heavier contractions.

Not been in labour yet though so I'll have to see how I go with it!

Don't forget to pack extra batteries in case you're in for a long labour!
