Potty Training my non-verbal son

My sons name is Elijah is 3 years old nonverbal. Although his nonverbal him and I have our own language. I have potty training him, now I’m working on how he communicates this to others when he needs to go! 
Here are some techniques that I use to help get him potty trained.
Proverbs 31:8 Speak up for those who cannot speak for themselves,
for the rights of all who are destitute.
