The science of toilet training: What research tells us about timing

When is the best time to showtime teaching children almost toileting? Infancy? 18 months? 24 months? Or even afterwards? What does the science of toilet training tell united states?

In that location is surprisingly little research addressing the question. And, as I note elsewhere, opens in a new windoweach age is associated with its own costs and benefits. Merely iii points seem articulate.

1. Information technology's possible to begin toilet train very early in life — if yous use methods that are condom and developmentally-appropriate.
2. Younger children may accept longer to master toilet preparation skills, so if you start relatively early on (e.thou., before 24 months), your child may may crave a longer duration of preparation.
3. Based on existing studies, more medical bug take been linked with initiating training later (afterwards 24 months) than earlier (before 24 months).

For the details, read on.

Studies advise that infant toilet training — expert safely and correctly — might protect kids from the development of bowel and bladder issues.

In many parts of the not-Western  world, information technology's traditional for children to brainstorm toilet training during infancy. How does this work? You can read the details in this Parenting Science article, merely the quick version is this: Families learn to communicate successfully about the timing of emptying. When a baby needs to void, the parent holds the infant over an appropriate receptacle, and gives the signal for the baby to proceed.

Does this practise — called "elimination communication" — cause damage? That seems unlikely. In fact, studies suggest that infant training reduces a child's risk of developing long-term bladder and bowel problems.

For example, consider Communist china, where elimination communication is the norm. In a sample of more than x,000 kids (aged 4-10 years), researchers there found that rates of bladder and bowel dysfunction were lowest for children who had started infant training earlier 12 months (Xu et al 2021). A similarly big study reports that that children who began traditional training prior to 12 months were less probable to develop overactive bladder later in life (Xing et al 2020).

At that place is as well an alternative, potty-chair based approach to babe preparation — 1 that tin can be attempted after a baby has learned to sit up on his or her own.  Information technology, too,  depends on realistic, gentle, historic period-advisable methods. You can read more well-nigh it here. Does this sort of grooming cause problems? I haven't found any systematic, scientific tests of this approach. But when investigators monitored the progress of infants in a small clinical study, they observed no adverse side effects (Smeets et al 1985).

Studies also hint that it's beneficial to brainstorm toilet preparation before a kid is 24 months onetime.

From the standpoint of avoiding medical problems, is it better to beginning training a toddler before he or she is 2 years old? Or should you await?

Recently, researchers analyzed the best evidence available — 10 different published studies, addressing a total study population of more than 24,000 children — and the trend was clear. Kids who began training earlier 24 months tended to savor meliorate long-term health outcomes.

It didn't affair if they had started out as young infants using elimination communication, or if waited until they were a chip older and begun with an age-appropriate, potty chair training method. Either way — every bit long as they had initiated grooming before 24 months — they were less likely to have developed urinary tract bug (Li et al 2020).

Do all studies say the same affair? No. I've found at least one piece of counter-evidence. In a study of 112 children, kids referred to a urologic clinic for voiding dysfunction were more than probable than symptom-free kids to accept been trained either earlier 24 months or after 35 months (Hodges et al 2014). Just the overall pattern — beyond studies — supports the thought that early trainees have a lower gamble of urinary tract troubles.

That doesn't mean that at that place's no downside to early preparation. Information technology tin be a lot of work for parents, and kids who get-go younger might take longer to attain toileting independence.

The work is especially axiomatic for elimination advice. Parents must be ever-vigilant and "tuned-in" to their infants' needs. But toddler training — using a potty chair — comes with its own challenges. For instance, some toddlers may try to suppress the urge to eliminate in social club to avoid a irksome visit to the bathroom. But it'southward an unhealthy habit — ane that can lead to constipation and urinary tract problems — then parents need to stay alert and encourage kids to use the potty many times each day.

It's also worth considering: Starting earlier might mean your child will take a fleck longer to complete training. Older kids have more than motor skills, and these skills help them speed through the training procedure. For instance, kids who are capable of pulling their own pants up and down may go into potty grooming with an advantage (Wyndaele et al 2020). And at to the lowest degree one study suggests that younger toddlers need more than time to learn.

In this report, Nathan Blum and his colleagues tracked more than 400 American children from the age of 17-19 months, checking in with parents every 2-iii months until their kids had completed daytime potty training. Training was considered "consummate" when children were wearing underpants rather than diapers, and experiencing a maximum of 3 urinary accidents and two fecal accidents per week (Blum et al 2003).

The researchers were particularly interested in the duration of "intensive" potty training, the sort of training that includes having your parent inquire you lot to sit on a potty chair at least 3 times per twenty-four hours. They likewise wondered if historic period at initiation fabricated a divergence, and so they compared 2 groups — kids who had started intense training before 27 months, and kids who began intensive training after 27 months.

And the issue? Both groups were equally likely to take encountered problems along the mode — bug like constipation, stool toileting refusal, stool withholding, or hiding from parents. But children trained earlier tended to take longer to complete grooming. Kids who starting training between xviii-24 months took, on average, 13-xiv months. Kids who trained afterward 27 months took 10 months or less (Blum et al 2003).

What if you wait longer, until your child is nigh three years old — or even older?

Equally nosotros've already noted, starting toilet grooming someday after 24 months has been linked with college rates of urinary tract dysfunction. And the evidence includes studies with large sample sizes, like one that one that tracked long-term outcomes in more than than 8500 kids (Joinson et al 2019). Merely does the run a risk continue getting higher as children go older?

Studies oasis't really addressed this point. We need more inquiry. But there are theoretical reasons to doubtable that earlier grooming could exist beneficial. When we urinate, it'south of import to eliminate all fluid from the bladder. It reduces the hazard of developing urinary tract infections. And toilet grooming? Information technology helps kids learn how to completely empty the bladder.

And then the earlier children brainstorm toilet training, the earlier they develop this salubrious habit (Janson et al 2000; Sillen and Hanson 2000). And the departure may be pretty dramatic.

In a cantankerous-cultural written report, researchers measured the voiding patterns of children living in Vietnam and Sweden. Most of the Vietnamese children had begun toilet grooming earlier the age of half-dozen months, and by 9 months, they had mastered the art of bladder-emptying: After an human action of urination, their bladders were completely free of any residual urine.

By contrast, 95% of the Swedish kids hadn't fifty-fifty started training past the historic period of 24 months, and these children didn't achieve complete emptying until they were 36 months old (Duong et al 2013).

Does the timing of toilet training have any psychological effects?

Yes, only the crucial factor isn't the child's chronological age. Instead, what'due south important is that you cull a fourth dimension when your kid is healthy (free of any urinary tract or bowel troubles) and ready to cooperate. And of course you must make certain that your goals and methods match your kid'south developmental capabilities. Regardless of your child'due south age, you want to make the process friendly and cooperative — not pressured or coercive. Punishments — for accidents or non-compliance — are always a bad idea.

But await, you might inquire. I've heard that early toilet preparation causes psychological problems. Isn't this truthful?

It's true that some people have fabricated these claims. But information technology'due south helpful to empathize the historical context. I doubtable that early potty training got a bad reputation because information technology was one time associated with harsh or coercive training methods.

In the 1920s and 1930s, parents were urged to impose a rigid toilet preparation regimen on children before they could walk. Techniques were coercive — sometimes even abusive.

I government transmission instructed parents to enforce "absolute regularity" of bowel movements by inserting a soap stick in the infant'south rectum at precise times of the 24-hour interval (United states Department of Labor 1935). Other prevalent tactics included scolding and concrete punishments for accidents (Hushka 1942; Stendler 1950; Luxem and Christophersen 1994.)

After World War Ii, the medical establishment began to decline early potty training. Freudian psychologists argued that early, rigid training caused emotional problems and neuroses later in life. And pediatricians, similar Benjamin Spock and T. Berry Brazelton, warned that pressuring children may cause a multifariousness of troubles, including stool withholding, stool toileting refusal, regression, and opens in a new window bed-wetting (Leiberman 1972; Brazelton 1962; Brazelton and Sparrow 2004).

So some child evolution researchers adopted the idea that training should non begin until kids could actively cooperate with the process (Brazelton et al 1999). Strict timetables for training were abased. Instead, parents were encouraged to let their children's spontaneous curiosity ready the step.

These changes probably saved many children from harsh training methods. But it seems to me that reformers fabricated the error of confusing methods with timing. For instance, in one historical study I've read, the author states that that any preparation before 10 months is, by definition, coercive (Hushka 1942).

What about this Freudian notion that toilet training causes psychological problems? It'southward interesting to note that Freud himself never singled out early on grooming as the crusade of personality disorders. He was concerned about any approach to training that might be regarded every bit extreme—too early, too late, besides strict, too "libidinous" (Fenichel 1945, p. 305).

And in any instance, I tin can observe no scientific studies that link the age of toilet training initiation with the subsequently development of emotional disorders. Freud identified certain personality types that accept been confirmed by mod scientific studies. However, these personality types have Non been linked to childhood toilet grooming experiences (Fisher and Greenberg 1977; Masling 1999).
