How did everyone start potty training their child/toddler and at what age?

First time parent here, I’m just wondering how everyone got to potty training their child — what worked, what didn’t work, what age to start? I have so much anxiety about this, but my son is 20 months and feeling like I should start soon. Any advice would be appreciated thanks! via /r/Parenting https://ift.tt/3eTmxcg
