My son turned 3 today, he’s a sweet boy. Anyways, this has everything to do with potty training. I have an 11year old step son that lives with us full time. He has been gone the majority of the summer, a month and half to be exact. My 3 year old did great this summer and had like maybe 2 accidents, and zero poop accidents. Well the older one came home Friday and in 2 days the little one has pooped his pants 3 times. I really don’t get it. He is about to lose all his underwear and pull ups at this point. On top of all of this, I’m pregnant with number 3 due at the end of September. I need some advice or something. I don’t get how we can’t do so good and be pretty much completely trained, and then in a manner of 2 1/2 days basically forget it all!
