This is, in reality, only his 8th or so bath, ever in his life. He hasn’t freaked out since the first one.
We use that mesh bandage stuff called Burn Net to keep his tubing up out of the water – both his PD Cath as well as, right now, the port access tube. Neither of those should be in the water where his butt has been. Then as soon as he gets out, I give him a dressing change on the PD Catheter.
