Please be careful with lending out Hypnobabies! I know from experience that if people don't value it, they aren't going to put the time and effort into it that is necessary to get the results they want. I lent my Hypnobabies Home Study materials to my sister and a several friends before I realized that even though they were really excited about it initially and appreciated being able to borrow it, they were less interested in it when it showed up on their doorstep for free. It was clear that some of them had never read any of the materials, and listened to the scripts in the wrong order entirely (or skipped some of the most important ones entirely). They all had ok births, but nothing like the birth I know Hypnobabies preparation can provide. Most of them admitted in retrospect that they wished they had actually done the preparation with Hypnobabies, rather than thinking about doing it and hardly ever getting around to it. Two of them went on to have lovely births using Hypnobabies for later babies, after they decided to purchase their own copies of Hypnobabies.
I urge you to think hard about how best to present the idea of learning Hypnobabies to your clients. It's one thing to recommend Hypnobabies and encourage people to use it, but I have a feeling if you lend it out, you'll be setting people up for disappointment as I did. There is just more commitment from people who make the decision to get ahold of Hypnobabies on their own. If you give it out, you'll also need to make sure that your clients who are using Hypnobabies know about all their options for getting questions answered and recieving feedback and support from women who have experience with Hypnobabies. Hypnobabies has many resources to help them with that, but if you give them the materials, they may view you as the authority on Hypnobabies, and not go to the proper source for complete and accurage answers to their questions. (Not saying that you don't know anything about Hypnobabies, just saying that if you're not an instructor, you probably aren't as knowledgeable as someone who is.)
