I have been lookingat labouring and possibly birthing in water and have learnt some valuable info to pass on to you all . . . Firstly its not actually recomended to get into a pool or bath till you are at least 4-5cm dilated as it can inhibit uterine activity and slow your labour down. plus the longer you spend in water the more dehydrated and exausted you become. Also temperature should not exceed 37degrees as this to can cause exaustion, high blood pressure, foetul distress and slowing of labour! So anyone planning on jumping in the bath as pain relief when it all kicks off might want to consider these two points!
