I love the sound of your homebirth!
The thing above all you will need is LUCK.
I had planned one also and had the pool and the rest of it.
Without sounding like doom and gloom, I think you also need to bring with you an understanding that the birth is a dance between your baby and your body. Sometimes with all the best preparations the dance is to a tune that isn't right for a homebirth.
For example: my waters broke with meuconium and my temperature went up and I was admitted to hospital and induced: labour was augmented and medicalised and we ended up three horrible crowded hospital days later with a botched crash cesarean. I only knew my midwife team, and just had a stranger - a hospital registrar to operate.
I thought everything would go brilliantly for me as I was all prepared for my homebirth, and had done yoga and was fit (as fit as you can be!! lol)had the drinking straws etc.. but my babe had other plans for me - she didn't like the crushing contractions and went into distress. Birth is a two person event (minumim!) sometimes your birth partners (your babe/s) have different plans.
thinking back, even though it would have seemed 'defeatist' IYSWIM at the time, i wish I'd been a little more realistic about birth, and that I'd packed a hospital bag, as I had to pack one when having contractions with meuconium spilling everywhere (even though I had a baby nappy in my pants) and my DH was in such a flap.
I have my fingers crossed you will birth your baby as you wish and hope your babe has that plan in mind for you also. Birth is not a willpower event, it's an organic dance that changes over time.
I loved labour, my contractions were fab and a bit orgasmic tbh!! but my babe didn't like it at all, and in the end she dictated to me how she would be born.
So I'm sending you LUCK because it's the most important thing to have.
