My son just turned one year old. We've been using the potty with him since he was 3 1/2 months old. Over the past couple of months he's gotten a lot better at communicating with us that he needs to go potty. From the beginning we've given him communication cues such as the ASL for potty: make a fist and place your thumb between your index and middle finger and move your hand back and forth bending at the elbow. We also make a pss pss sound which Levi will sometimes imitate. We also say potty and Levi will say pa pa if he needs to go. I just thought I'd share some video of Levi doing his signs today.
When he does a sign we take him either to the potty insert on the big toilet or his little potty on the ground in his bedroom. (My husband likes the one in the bedroom more because we can sit in front of him and look at books or play with toys.)
Sometimes we won't even have to ask him and he will look at us and shake his hand. If you don't know what you're looking for it's easy to miss.
Just chillin on the potty. It's just a typical part of his day. (Daddy got him this toy for his birthday.)
