Kellie, there is no real reason to expect to have another epi this time around, although scarred skin doesn't stretch as good as un scarred skin. You can use epo on your perineum as it helps to soften scar tissue. You can take them orally and also massage it into your perineum.

Water is great to help support your body as you are birthing. What hospital are you going through.

As for your waters leaking. Well they won't know how long it's been leaking unless you tell them will they

Great support is a good thing to have when you are birthing, it really can make all the difference. I know you said you can't afford private help, but you could perhaps look into getting a trainee doula, someone who you don't have to pay. Work's out great for both of you then.

Goodluck hun and I'm sure all will be fine.
