Poop problems
Toddler pees on the potty but won't poop on it
Very common. Pooping feels bigger and scarier than peeing, and it's one of the few things a toddler fully controls. Pushing harder usually makes them hold it in longer.
What to do this week
- Daily poop sit 15 to 30 minutes after a meal, feet on a stool, a book in hand.
- Asks for a diaper? Let them poop in it, in the bathroom. Then move to sitting on the potty with the diaper on.
- Stop asking about poop. Praise every sit, not just results.
What to say
“Your poop wants to come out. Let's let it out.”
Try not to say
“Big kids don't poop in diapers.”
When to call your pediatrician
- Pain or blood when pooping
- No poop for 3 days or more, or fewer than 3 poops a week
- A swollen or hard belly, or vomiting
- Poop smears or leaks in underwear after being trained
- Poor appetite or weight loss along with constipation
