Laboured in water twice, would recommend it!
Had to get out after a while with my first as baby got a bit stuck and needed extra monitoring etc.
With the second I got in when about 7-8cm and had an actual waterbirth.
In both cases I was lucky to get the pool as no one else was using it, just luck of the draw.
My water experiences were brilliant. I had gas and air with both. I had huge bumps and found it a lot easier to move around in the water.
With the second I gave birth on all fours in the pool, baby just eased out and no fuss. She didn’t even cry at first until we lifted her up out of the water and she got cold!
I did apparently do a little poo in the pool
but midwife fished it out with a little jug and chucked it away before I even realised!
They were careful to check the water temp and top up the hot water regularly. It was a bit alarming right at the end when blood turned the water red but I got out straight after baby was born and delivered placenta on dry land so to speak.
Waterbirth was so calm and more confortable compared to first child where I had to get out and give birth on my back on a bed.
Even if you can just use pool for labouring I would recommend it.
