Unsupervised Bathing

[earthflower]

My almost 5 year old son has just stated being in the bathroom/bathtub alone for a few mins at a time, he took swim lessons throughout the whole summer. I would rather be in there still because then there is less water being used and it stays in the tub, he would rather I stay in there so we can play with his bath toys lol. My older son 8 takes showers in my bathroom now, so he does it all alone w/ the bathroom door shut. I don't think I ever left him alone when he was little.
