Hypnobirthing and other labour tools
Like anything in life, many of us feel better about labour if it's something we can prepare for. Everyone wants to avoid the pain and agony horror stories and one technique that many have embraced (including mums who already had one stressful childbirth), is hypnobirthing, which teaches mums-to-be visualisation and breathing techniques to help them through labour (Kate Middleton is reportedly a fan of this technique). You can book into private classes, and many hospitals are now offering hypnobirthing courses as well – if you're interested, check out Hypnobirthing: The Mongan Method for some nighttime reading.
Also, Ina May Gaskin (a US midwifery guru)'s book, Spiritual Midwifery, is worth a read: all about empowering and enjoying labour (warning: there are orgasmic labour stories), it's a real eye-opener with positive birth stories that show a completely different perspective on birth than the one we're used to hearing about.
When it comes to pain-relieving techniques in childbirth, some swear by TENS machines (transcutaneous electrical nerve stimulation), which can help alleviate pain or at least distract labouring mums, and can be bought or rented. We'd also suggest buying a range of essential oils: clary sage if you're overdue to help stimulate labour, lavender, lemon and peppermint for labour, which can calm and energise exhausted and stressed mums, and tea tree oil for post-birth recovery.
