Potty training boys: a few practical notes
The chart is the same for every child; what changes with boys is mostly the order of a couple of steps and a few practicalities. Pick a theme he loves and let the stickers do the rest.
Sitting first, standing later
Most boys learn to wee sitting down first, which also makes poos easier because the two often come together. Standing can come months later, once he's reliably dry. There's no need for a "standing up" row on the chart until then; when it's time, add "Aimed in the toilet" and expect to clean the floor for a while.
Poo takes longer
It's common for boys (and girls) to manage wees weeks before poos. Keep "Did a poo" as its own row so it's clearly a separate success, and don't let the chart make him feel behind for that row staying empty. A single sticker there is a big day.
Themes that get him to the bathroom
Dinosaurs is set here because it's the most asked-for. Space, sports, ocean and farm animals are a click away in the Theme section. The pictures next to each step come from the theme; click one in the list to choose a different one, say the T-rex for "Did a poo" if that makes him laugh.
Rewards
Stickers usually carry the first fortnight. If you add a reward, make it reachable in days, not weeks, and write it on the chart. Avoid tying it to "no accidents"; accidents are normal and the chart should only ever add.
Night-time is separate
Staying dry at night is a different developmental step and often comes a year or more later. Leave it off the chart until he's regularly waking dry, then add "Dry all night" as its own row with its own celebration.
