I have had two hospital births, both unmedicated. Here is why I am planning a homebirth this time:
1 - I hate the fetal monitor. I am allergic to the gel (or something like that) and nobody believes me - I get huge welts two days later over wherever they put the monitor. And I hate it squeezing me.
2 - I hate having my blood pressure taken. It is especially annoying in transition, and doubly so when they keep trying because 'they need a reading but can't get one during a contraction' and um, this is obviously impossible because the contractions are coming so fast...
3 - I don't want my mom to have to fight with the nurses about what position I "can" push in.
4 - I don't want to have to fight to avoid drugs, episiotomies, tugging on the cord, etc (managed to avoid all of this both times, but it was a fight).
5 - Once the baby is born, I don't want to move to another room. I don't want him/her removed and weighed. I don't want him/her cleaned. I don't want him/her medicated, eyedropped, temperature-taken, slapped, checked-out, or anything. I want to hold my baby - NOW and I don't want my mom to have to grab the baby from the doctor to get that!
6 - I want my daughter and son to be able to choose between playing in their room/with their nana/whatever and watching the birth.
7 - I don't want to wake up every hour on the hour all night to get my blood pressure and temperature taken.
8 - I don't want to fight nurses over how they bathe my baby. I don't want their advice on how to care for my baby (for the most part).
9 - I want to sleep well our first night together. I don't want to be in a strange place, freezing my butt off, with DH in a separate bed, with nurses waking us every hour, sleeping if I'm exhausted (which I wasn't with my second).
That's all I can think of for now but there are a million reasons.
