The Pink Kit

I am 37 weeks pregnant with my first & trying to get feedback on the Pink Kit, which is a methodology for active birthing, helps reduce time in labour, need for drugs, tearing etc. Has anybody in Auckland-Whangarei district used it? I live in Waipu, near Whangarei & would love to hear from anyone who has a copy & has used it, & also which midwives in the district have used it. Its $90 to buy for a one-off event, not sure if I want to shell out the cash if someone out there already has a copy & they've already had their baby/s ... Any help appreciated, thanks Nadia
