Nightmare morning, ugh

So we are currently potty training our son who turns two in May. We leave him naked and then have him sit on his potty often. Well today I left the living room to use the bathroom (literally like 2 min tops) and he comes running telling me something in his babble. I go over and see he pooped all over the floor then tried cleaning it with his pants! He had poop on his hands too. Ugh! So I threw him in the bath, and let him play in there while I cleaned the mess. (His 7 year old brother was in the bathroom with him) all of a sudden my 7 year old starts shouting “ewww no!!” I run over and see he now pooped in the tub with water in it! OMG! It was such a mess and to top it off my husband wasn’t home. I could barley bare the smell. I literally feel lightheaded now from everything that just went on. Currently 10 weeks pg so not my ideal morning when I’m already nauseous 😪🤮🤢
