I must say; that would have been it for me. Between the increasingly alarming behaviour, the poop smearing (I really think that at the age of 2 that was something he KNEW was wrong. Even my one year olds think poop is "ucky"), mom's reaction when you called and dad's ABSOLUTELY IGNORANT (!!!!!!!) response..... nope, that's enough.
God bless you if you feel like you can continue, but not me. Moving forward, though, I would have little to no tolerance from mom/dad and little man at this point. No apologies, no clear willingness to deal with these issues (I'm sorry; "lock him in a room for a timeout"??? Calling him a bad boy, and that is it??), NO RESPECT for you or the position that you are in ie: poop everywhere and other children to care for.
I hope for your sake that this was a turning point for this family. If not; you deserve better. You are RAISING THESE PEOPLE'S CHILD, for crying out loud!!!
Sorry for all the capitals, I just got really fired up on your behalf reading this story, lol.![]()
