I don't think there is a best age. From what I hear, if you start when your child is showing an interest, it can take very little time. However, you can also start very early with them! The youngest i have started is 9 months. She still wears diapers, and only went in the toilet about 1/2 the time, but I saved a TON on diapers. She goes every single time I put her on the toilet, so she fully understands what it is for. She is now 16 months and I have been putting her in underwear and working on getting her on the toilet every time! Like I said, it may not take as long if you wait until they themselves are interested, but they can learn to go at a MUCH younger age. It just takes a little/lot more work.
