Yesterday, after hearing several unauthorized splashing sounds, I went to check on the boys in the bathtub. Sure enough, they were giggling and dumping water on each other with a bucket. The fact that the water was blue from being saturated by bar soap did not seem to deter them.
And then I realized that the bucket that they were so gleefully playing with was Greggory's training potty!!
But with all that soap in the water, I just figured the soap and the potty canceled each other out.
