We read with great interest the article by Mota & Barros on toilet training in Brazil.1 The authors expressed their concern regarding early toilet training and possible adverse events. They based these concerns on two articles2,3; we read both articles thoroughly and did not find any mention of adverse events connected with early toilet training. On the contrary, Luxem & Christophersen concluded that “empirical data suggest that early toilet training is physiologically possible and behavioral techniques might be developed to train the younger child and that they can be made practical and socially valid,”2 and Taubman3 noted an “association of this behavior [stool toileting refusal] with toilet training at a later age.” Moreover, Taubman refers to pre-Brazelton “coercive toilet training practices that were prevalent in the United States.” Assisted infant toilet training (AITT) and related methods are dramatically different in that there is no enforcement involved; instead there is gentle attention given to the child's elimination signals and needs.4
Mota & Barros1 wrote, “we know that it is not possible to accelerate the development and myelination of nerve fibers, which are necessary to acquire this control, and that the child needs cognitive development to be able to understand the mechanisms involved in acquisition of urinary habits, and also how to adapt to the local culture and socialize.” They base these claims on an article by Hellstrom et al.,5 but this article is a survey and not a research of myelinization or development of nerve fibers. While Brazelton stressed that myelinization of the pyramidal tracts of the central nervous system must be complete, occurring in his opinion between 12-18 months, Luxem & Christophersen2 argue it is probably present by the time a child crawls, and, based on cross-cultural studies, they conclude that toilet readiness is determined more by environment than neuroanatomy. Moreover, Hellstrom et al. suggest in another article6 that late rather than early toilet training actually might result in bladder dysfunction.
Methods of early toilet training such as AITT (also called “elimination communication”) are widely used in Asia and Africa. Various studies have shown that toddlers and even babies are capable of staying dry when allowed other options more befitting their developmental status.4,7 Despite their underdeveloped nervous systems, babies can grasp the mechanisms of urinary functioning well enough to display elimination signals and satisfaction when offered a potty.4,7 A neonate will squirm or cry when feeling the urge to empty its bladder or bowels. An older baby will gesture, and if possible crawl in the direction of a potty; a walking toddler may walk to a potty and sit down. When a baby is diapered, these signals are misinterpreted and ignored. An attentive parent can recognize these gestures and assist the child.4
An international study of 286 children who started toilet training during the first year of life revealed that over 90% showed elimination signals; mean completion ages for daytime dryness and bowel control were lower than 18 months, and no negative side effects were reported.7 Compared with Western toilet training (started around 2 years of age), stool toileting refusal in AITT drops from 22 to 12%.7
We believe that AITT offers a healthy alternative to contemporary toilet training. The child can enjoy more mobility without a cumbersome diaper, will suffer less skin rash and may develop better bladder function,6 while child-parent communication is enriched, and ecological damage caused by disposable diapers is reduced.
The current ecological and economical situation calls for such an alternative, especially in countries where a large part of the population has limited financial resources, like Brazil.

We are grateful for the interest that Dr. T. Sahar and colleagues have shown in our work. One of our objectives in writing a series of articles on this subject is to draw the attention of both pediatricians and researchers to the issue of toilet training. This is a very stimulating subject in which cultural variations intermingle with physiological and behavioral characteristics.
In 2003, while conducting research into micturition habits,1 we detected that there had been an increase in the prevalence of voiding dysfunction among preschool and school aged children over recent years. Some of the articles that we reviewed suggested that toilet training might be a possible predictive factor for voiding disfunction. We therefore decided to review the literature2 and to conduct a longitudinal study of the subject using data from a cohort of children born in the city of Pelotas in 2004 and who are being followed. To date we are in possession of data relating to assessments of these children at 12 and 24 months, which have led to two articles.3,4
In order to be in a position to reply to the questions raised by Tali et al., it is necessary to first point out that our study took into account the strategies actually used by Brazilian mothers, which have nothing to do with the assisted infant toilet training techniques (AITT) that these authors recommend. In the Brazilian setting, which is probably very similar to many other Western countries, we observed that a considerable percentage of the unsuccessful attempts at toilet training were initiated before infants reached 18 months of age. Our adjusted statistical analysis demonstrated that previous unsuccessful attempts at toilet training were associated with a reduced chance of being toilet trained by two years of age. Summing up, our results suggest that starting training before 18 months of age may delay the acquisition of bladder and bowel control. Of course, we are not dealing with data relating to other cultures, where completely different strategies are described.5 There is still limited evidence that this particular strategy can be used in a western cultural context.6
Our concerns with relation to the possible adverse effects of toilet training are not limited to premature attempts at training, but rather include a variety of inappropriate forms of training, like late toilet training, dispensing with the use of a child-sized toilet seat and/or a foot rest and also coercive and punitive attitudes.
With relation to the issue of neurological maturity and the acquisition of certain abilities, we do believe that these are important factors and that the abilities listed in previous publications2 and dealt with by Schum et al.7 are a guide here. However, it is important to point out that the ultimate objective of our approach to toilet training is for children to attain an independent status in which they are capable of maintaining themselves dry and clean without aid or with aid limited to specific tasks.
Finally, we reiterate that we are not criticizing the AITT method and that we will wait for further scientific evidence of its results, in terms of success of its use and the absence of undesirable effects. Our research is also ongoing and we are currently evaluating data referring to the now 4-year-old children, in order to observe whether inadequate toilet training may indeed be related to symptoms of voiding dysfunction. We need this evidence urgently so as to enable pediatricians to correctly advise mothers with relation to the most appropriate strategies for toilet training safely without leading to future problems, bearing in mind that existing methods have not been adequately tested or compared with one another.
