Potty training,
start to finish.
When to start. What to buy. The three-block method. The honest truth: most resistance is parents over-prompting. A calm, day-by-day plan, with the scripts that work and the ones that don't.
Glowacki's guidance — and the consensus across three popular methods:
- Start between 20-30 months. After 30 months, growing independence makes it exponentially harder.
- Your confidence and commitment are the single most important variable.
- Always prompt with a statement. Never ask "Do you have to go potty?""¿Tienes que hacer del baño?"
- Pull-ups are diapers. Don't use them in active training.
Potty training has the dubious honor of being the parenting topic that produces the most contradictory advice. Three popular methods — Glowacki, Jenner, Swaney — disagree about rewards. They disagree about timelines. But on the bones of the thing, they agree completely: start before 30 months, be confident, prompt with statements, and ride it out.
§ 01 When to start
Readiness signs
- Retreats to a corner or hides to poop (associates pooping with privacy).
- Shows awareness of a wet or dirty diaper — tells you, pulls at it.
- Can follow simple instructions.
- Can communicate basic needs — verbal or nonverbal.
- Stays dry for longer stretches.
- Shows interest in the toilet or watches others use it.
- Does a "pee-pee dance," grabs themselves, or squirms before going.
- The first month after a new baby is home
- A move to a new house
- Active illness with diarrhea or constipation
- Major family upheaval
§ 02 Two weeks before — your mindset
All three experts agree: your confidence is the variable that matters most. Your child absorbs your energy. Anxious parent, anxious child. Decisive parent, child follows.
- Get your partner fully on board. Two different approaches confuse the child.
- Clear your social calendar for the first week.
- Communicate the plan to daycare and grandparents — consistency across environments is critical.
- Don't post on social media asking for advice. You'll get 34 contradictory opinions.
Supplies
- Potty chair (or trainer seat + step stool).
- 20+ pairs of cotton underwear, 1-2 sizes up for easy pull up/down.
- Elastic-waistband pants only — no onesies, overalls, or buttons.
- Waterproof mattress protector.
- Portable potty for the car.
- Child-friendly hand soap.
- A potty training storybook to read nightly in the lead-up.
Prep the child
- Start casually: "On [day], we're saying goodbye to diapers.""El [día], le vamos a decir adiós a los pañales."
- Let them come to the bathroom with you to normalize it.
- Read potty books at bedtime.
- Practice pushing pants down — say pushempujanot pulljala; toddlers are literal.
- Talk up "big kid" things they already do.
§ 03 The method, day by day
Day 1 — naked at home.
Remove the diaper. Be matter-of-fact: "Today you're going to put your pee and poop in the potty.""Hoy vas a poner tu pipí y tu popó en la bacinica."Naked from the waist down all day. Your only job: watch. Push fluids gently. Wait for pee to start, then rush to the potty. Over successive pees, they'll give more warning — a look, a pause, a grab.
Days 2-3 — clothes on, commando.
Add clothes but NO underwear. Underwear feels like a diaper and triggers the "release" muscle memory. Elastic pants only. Start small outings. Get a good pee before leaving. This is the hardest phase — most parents want to quit here. Keep going.
Days 4-7 — solidify and venture.
Longer outings. Visiting friends. Daycare transition. Bring the potty in the car. If they say they need to go, drop everything — you have 5-10 seconds. Learn their pattern. Some kids are camels; some pee every 30 minutes.
Weeks 2-3 — self-initiation.
Verbal self-initiation takes about three weeks. Switch from commando to underwear after about a month. Stack successes. Celebrate what's going right.
For poop on day one
Watch for the concentration face, grunting, retreating. Get them on the potty with a book. Put thick books under their feet to mimic a squat — feet need to be supported.
Prompting: "Come, it's time to pee.""Ven, es hora de hacer pipí."— never "Do you have to go potty?""¿Tienes que hacer del baño?"
After accidents: "You peed on the floor. Pee goes in the potty.""Hiciste pipí en el piso. La pipí va en la bacinica."Simple, neutral. No scolding. No "it's okay.""no pasa nada."
After success: "You did it!""¡Lo lograste!"or simply: "You peed in the potty!""¡Hiciste pipí en la bacinica!"
When they refuse a prompt: "Okay, I trust you to come tell me when you do. I'll be in the kitchen when you need me.""Okay, confío en que vengas a decirme cuando lo hagas. Voy a estar en la cocina cuando me necesites."("when," not "if.")
§ 04 Prompting — the key skill
The single biggest mistake is asking instead of prompting. Toddlers will say "no" to a question every time. Use statements.
| Don't say | Do say |
|---|---|
| Do you have to go potty?¿Tienes que hacer del baño? | Come, it's time to pee.Ven, es hora de hacer pipí. |
| Do you need to use the bathroom?¿Necesitas usar el baño? | Let's pee before we go outside.Vamos a hacer pipí antes de salir. |
| Want to try the potty?¿Quieres probar la bacinica? | Sit on the potty, then we'll wash hands for lunch.Siéntate en la bacinica, y luego nos lavamos las manos para comer. |
Cluster prompting works well — bundle it with other transitions: "Pick up your blocks, it's time for lunch, go sit on the potty.""Recoge tus bloques, es hora de comer, ve a sentarte en la bacinica."
Toys help: "Truck, you wait here. She's going to pee and will be right back.""Camión, espera aquí. Ella va a hacer pipí y ya regresa."
§ 05 The rewards debate
This is the one place the experts disagree. Pick what fits your family.
- Rewards create power dynamics and external dependency.
- Natural pride and accomplishment is the reward.
- Have them say "I did it!""¡Lo logré!"
- Let them dump the potty into the big toilet — flushing is intrinsically rewarding.
- Stars in a jar, sticker charts.
- Wrapped prizes at milestones (5, 10, 15 stars).
- 1 star for sitting, 2 for pee, 3 for poop.
- Makes it fun and exciting.
Swaney's middle path: consider your child's love language. Some thrive on verbal praise. Some on high-fives. Some on stickers. Match the motivation to the child.
§ 06 Routine anchors
Take them to the potty at every transition:
- Upon waking
- Before and after meals
- Before and after snacks
- Before leaving the house
- Upon arriving somewhere
- Before and after nap
- Before bath
- Before bed
Don't rely on a timer alone — it creates a sound association rather than bladder awareness. Use observation as the primary guide. Don't let them sit longer than 1-2 minutes if nothing's happening; you don't want "sitting on potty to please parent" to become the pattern.
§ 07 Night training
Wait until daytime is solid — at least 2 months of consistent daytime dryness (Jenner). Some kids are ready simultaneously; many aren't.
- Night light + potty near the bed.
- Waterproof mattress protector + spare sheets ready.
- Reduce fluids 30-60 minutes before bed.
- Sit on potty 3-5 minutes before bed (with a book).
- Loose pajamas — no all-in-ones.
- Reward the effort (sitting), not the outcome (dry night). They cannot control overnight bladder yet.
Timeline reality: children can be up to 4-5 years old before consistently dry at night. This is normal and physiological. Not a failure. Not a phase to fight.
§ 08 Common pitfalls
"Waiting until they're ready."
Glowacki's view: the biggest mistake. After 30 months it gets much harder. Don't wait for a signal that may never come on its own.
Switching between diapers and underwear.
Pick a day and commit. Going back and forth sends mixed messages.
Pull-ups during the day.
All three experts agree: pull-ups are diapers. Don't use them during active training.
Overprompting.
Asking every five minutes creates resistance and power struggles. 90% of resistance is caused by overprompting. Prompt at transitions, then back off.
Asking instead of prompting.
"Do you need to go?" invites no. Use statements.
Getting angry at accidents.
They'll associate the potty with fear and shame. Stay neutral.
Putting underwear on too soon.
It feels like a diaper. Stay commando for about a month.
Not being consistent across environments.
Daycare, grandparents, outings — same approach everywhere.
Screens on the potty.
Don't create a long-term electronics-on-toilet habit.
Expecting instant self-initiation.
It takes about three weeks. Prompting is normal and necessary at first.
§ 09 Poop is its own project
Poop is often harder than pee. Kids may withhold or ask for a diaper specifically to poop. This is so common it's nearly universal.
- Feet supported. Books or a stool under the feet so they can push (squat position).
- Privacy. Some kids need you to step back.
- Personify it. "Let Mr. Poo Poo come out and go for a swim!""¡Que salga el Sr. Popó y se vaya a nadar!"
- Let them flush. Dumping the potty into the big toilet is intrinsically rewarding.
- Timing. Watch for after-meal patterns; most kids poop at predictable times.
- Encouragement while sitting: "It's coming, you can do it. Just relax and let it fall out.""Ya viene, tú puedes. Solo relájate y deja que caiga."
- If they're scared: read together, blow bubbles, sing.
Boys
- Train sitting down first — standing requires aiming and holding, too much coordination at first.
- Hold penis down while sitting; explain what you're doing.
- Standing comes naturally later. Don't rush it.
§ 10 Phrases to retire
| Stop saying | Why | Try instead |
|---|---|---|
| It's okay! (after an accident)¡No pasa nada! (después de un accidente) | Minimizes and confuses. | You peed on the floor. Pee goes in the potty.Hiciste pipí en el piso. La pipí va en la bacinica. |
| You're such a big kid!¡Eres una niña grande! | Ties bodily function to performance and identity. | You did it!¡Lo lograste! |
| Don't you want to be a big kid?¿No quieres ser niña grande? | Shames them for not being ready. | On [day], we're saying goodbye to diapers.El [día], le vamos a decir adiós a los pañales. |
| Yucky! / Ew!¡Guácala! / ¡Iuk! | Teaches their body produces something disgusting. Can trigger withholding. | You pooped! Let's flush it.¡Hiciste popó! Vamos a echarlo al baño. |
| Just try harder.Esfuérzate más. | The issue is skill, not effort. | Your body is still learning. We'll keep practicing.Tu cuerpo todavía está aprendiendo. Vamos a seguir practicando. |
| Why didn't you tell me?¿Por qué no me dijiste? | They may not have known. | Next time your body feels like it needs to pee, come find me.La próxima vez que tu cuerpo sienta que necesita hacer pipí, ven a buscarme. |
