I had started to potty /pee-pee train my son, since he was one and half year old.
For potty it was very hard to make him sit at the begining, but I was aware of his regular routine. He went potty every morn after breakfast. So I knew the time to make him sit on the potty. I sat with him at the potty every morning for abt 20 minutes over there. But well this is how he would get comfortable with the potty seat and then he would go. Of course he used to get constipated and juices are the best option for that.
Also my son prefers peace while he goes, so while he is doing the potty, he will ask me to go out, so I guess they also require privacy , just leave the door open and stand on a side, without making noise for him to concentrate and after a few days he will himself come to u and tell u that he requires to go potty.
I feel u just require to give him some practice before his potty time, and make him seat on the potty seat more often
