nothing to be nervous about... my first class was about childbirth,MW sat there with a plastic pelvis, a dolly and a placenta talking us through how the whole process worked, chatting about this & that in between.
2nd class was about various pain relief options available to us..
3rd was/is a hospital tour, but i wont be going to that..as ive already been on it
there is a 4th class, but i think thats about BF and something ive done my own research on and have come to my own decision about.
