Potty training

Latosha • I`m 26. Married to my husband 8 years. We have two August boys. Mason who is 4 and Eli who is 1.

How would you know when your little one is ready to potty train? My 20 month old runs to me and says “booty” when he has pee or poop in his diaper and wants me to change it. I want to start training him but not sure where to start. Just curious how other moms did it and what age they started.
