I have all tile, and if she were young, i'd use a potty chair. So, while I wouldn't have helped you until about now, I am one of those who believes a child can do this by age two. It's not even hard unless you wait too long.
However, I CAN tell if a child will be able to do it or not. I have a guy who will be three in September, and he will not likely be potty training any time soon. He's nowhere near "getting" it.
But, I can have other kids do most of the potty training for me.
Seriously, I put the four year olds on it, and they get the child potty trained in a day or two. Every time one of them has to go, they invite the newbie, so we all go in there and make a party of it...it's somehow fun for them.
Personally, I think kids in cloth diapers train earlier than kids in the sposies anyway.
And, I hate the term potty learning. LOL So, I was all excited when you said "cloth diapers" and "Potty training" in the same post.
