hi! i had a home birth three weeks ago and ended up not using any gas and air or pain relief, it wasn't the easiest thing i've ever done but good fun!
I gave birth in a birth pool in a box (great as my husband could get in with me) and them temp is about 37 degrees, we filled it up in the morning and i got in when the midwives arrived and i was 5cm. we had a heat retaining cover to keep it warm when i wasn't using it. but once i got in there, wow i was panicking before hand as it was getting intense and once i jumped in the pool.....i can't even describe the relief! the warmth, and pressure of the water and being able to float and be weightless just took the edge of everything.
i then used hypnobirthing techniques to go into deep relaxation and breathe through the contractions, this was only possible when the room was quiet and i didn't have any distractions, so i kind of went in and out of the deep relaxation a bit! my husband massaged my back and stroked my arms etc which helped too.
i think doing the hypnobirthing classes helped me prepare so much mentally for the birth, i didn't feel scared about things going wrong and believed that my body could birth my baby and that mindset i think had a lot of answer for in me getting on with the birth and letting it flow,
there were a couple of moments were i had tears and said i couldn't do it, but then you have to let your mind go and your body take over, my phrase during labour was 'i just want a break for a bit!!) but as manummum says a firm midwife is good! mine told me to breathe etc when i panicked during transition and i did what she said haha!
my mum is a hypnobirthing teacher and doula so i had her to help me along the way and during the birth, i do reccomend having as much support as you can get! doula's are ace!!
Good Luck hun! Sure your birth will be fab!
