Potty training!?

Terra

Anyone have any tips or tricks?? Potty training a 19month old. Currently I’m taking him every 15mins to the potty he usually pees and loves to try and use the potty but he doesn’t tell me when he has to go and if he goes without a diaper he thinks is hilarious to purposely pee on the floor. He will even stop and push until he pees just to do it on the floor. I also have a 6week old so anything to make my life easier would be great!!! Thanks on advanced mommas
