Types Of Enemas

What is the safest? I do not want to try castor oil

Enema will not do you much good, either, except clean your system very well.
The only "proven" ways of getting work in progress is nipple stimulation because it releases the same hormones that trigger labor, sexual relations from chemicals in semen may help ripen your cervix uterus, and a lot of walking since the gravity that helps make the baby down into your pelvis so that the baby is in a position to work optimally.
None of these will work if your baby is not ready to be born ... Good luck with your little pixie ... I was like 40 weeks now!

Fleet enemas are the most common preparation for surgery, etc. This is one I recommend.

enema will reveal a shit, not a baby .. Just cold, it'll happen when it happens ...
