Back when my oldest was about 12 or 13, (she's 19 years old now and is tiny -- 5' 3' and only 115 lbs) but she pushes out the biggest shits I've ever seen. So much so, that I got so tired of unplugging shit-clogged toilets that I replaced the toilet in the "kids" bathroon with one of those pressure assisted models that use compressed air to shoot the shit down.
I put that in about 5 or 6 yrs ago, and problem solved. Only thing is you can hear the damn thing flush from down the street.
