I need all the potty training advice for potty training my 3 year old boy. He just turned 3 and is showing clear signs of being ready so I know it's the right time. Plus his doctor agrees he's ready. He wears underwear during the day when we're just hanging out at home and will sit on the potty but won't go, as soon as he's back in his underwear he will pee. Let me know what tricks worked for you or what advice you have. I have 2 older children but I truly can't remember how I ended up potty training them. My daughter basically just sat in the potty and went and enjoyed underwear instead of her diapers but I don't recall how I potty trained my other son(he's my oldest and so it's been many years since I potty trained him)
