Tell me about your early potty training experiences!

My son is 20 months old and I am wondering if it is time to think about potty training? For the past few days he will tell me "stinky" and "poop" about 30 seconds before he poops. He also says "pee" when I am peeing in the toilet. So I feel like those are good first steps!

Has anyone taken the slower/less pressure approach to potty training? Or should I wait until he is a bit older and really focus on it? What resources do you recommend? He has a great vocabulary and is clear telling us what he needs. Any advice is welcome!
