Potty training? Help!

Ashley

So my son is about to turn 3 February 20th and I’m trying to get him potty trained but don’t even know where to begin. He tells me when he’s pooped and peed in his pull up and I tell him you have to tell me before you use the potty in your pants and I’ve sat him on his toilet multiple times and he just pretends he’s potting and get happy lol he says “yay I potty” and I just tell him good job But what else should I do to get him on track with it?
