I've only heard of hypnobirthing, haven't heard of hypnobabies. Our doula recommended some hypno birthing CD's that I listened to before birth. Lots of guidance and relaxation strategies, putting in positive statements, (rather than the loads of horror stories that you hear when you're pregnant). The CD's that I listened to started off with early pregnancy and then preparing for labour and there's one for when you're in labour. They're great to listen to before bed and when you're in labour.
