What is the right age to toilet train your baby? 12 months, 18 months, 24 months? Later?

There is no right age. Each child grows at a different pace. It depends in your child. Is your child able to communicate, able to have dry diapers during his naps, able to differentiate between pee and poo? All these are the tell tale signs he maybe ready to start toilet training. Also you can practice and put him on the potty for a start.
