I was at a Christmas party some years ago and a plumber was there as one of the guests. (He was the best dressed guy at the party.) As luck would have it, one of the kids stopped up a toilet and he was able to quickly fix the problem. He told the host that he was fortunate he was there because paying for his services on Christmas Day would have been incredibly expensive. LOL
My plumber told me to take a stool softener.
Not a plumber but as a father of four, I've mastered the art of removing a toilet to dislodge whatever item my kids tried to flush only to get jammed up in the toilet trap.
I keep a spare wax wing and some flanges and bolts in the garage to save me a trip to Home Depot.
If solids plug the toilet, put plenty of dish soap in the toilet, let stand a while, and then plunge. Works every time.
