Heat packs safe to use in labour? Any particular brand?

[HannahNeale]

Just thinking of some heat packs for my back as it would be easier to travel to the hospital with those than a hot water bottle! Just wondering if anyone's used them and which ones are safe?

Do you mean the type you press and create a chemical reaction that heats on it's own? I don't see why they wouldn't be safe. Sometimes they can get quite hot but you could just wrap a cloth around it or keep it on top of your clothes if needed. I had a home birth last time and used a grain bag that heats in the microwave all the way through my labour and it was great but I quite like the idea of having some self heating packs on hand.
