E.M.
I switched; my son turned two in July. Right now he could care less about using the potty at home, but has used it twice successfully at daycare.
I switched because I was tired of all the waste I was contributing by using disposables and for potty training.
I admit he does say that he went to the potty right after he pees. I know we have a long way to go and he is still young but I think it was the right choice for me.
I use prefolds, fitted and AIO.
