I took Lamaze classes with my first 2 and the third was such a surprise, 13 moinths after the second, there was no time. I never had any drugs, and I credit the relazation techniques learned at the class for being able to do all that without meds. I've used the same techniques over te years for other painful procedures
I went from being in labor 20 hours with the first to practically having my daughter in the labor room
With all 3 I went from being dilated 3 cm to 10 in 3 minutes, there was no time for pain meds
