7 myths about Potty Training that you probably still believe

Separating fact from fiction isn’t always easy where potty training is concerned. So how much of what you think is based on research? Explore these 7 common myths about potty training and test your knowledge.

Here at Little Bunny Bear we take evidence-based advice very seriously. We don’t just provide opinion, but instead bring you information based on sound research, so you can make up your own mind based on the facts.  You’re welcome!

Myth 1: Early potty training causes constipation, withholding, toileting refusal and psychological damage

Fact: It is the way a child is potty trained that counts, not how soon you start. Using a gentle approach that works at your child’s own pace does not cause these problems. There is no proven link in the research between constipation, withholding and toileting refusal and early potty training. Instead, earlier potty training is shown to reduce the risk of constipation, stool holding and toileting refusal (Blum 2003).

Research shows that starting to learn potty skills even as early as birth has many benefits (Kaerts 2013, Rogers 2002). When done gently and in response to a childs natural instincts, infants can be potty trained by 12 months with no reported side effects and can potty independently by 24 months (Duong 2013).

The things that are proven to be harmful include: provoking voiding by running the tap,  encouraging “pushing,” (Bakker et al, 2002),  power struggles and the use of rewards and punishment (Stadtler 1999, Taubman 1997.) Many of these problems can be avoided by starting early and ensuring that using a potty is a normal part of your child’s every day routine.

Myth 2: a child must be “ready” before they start potty training

Fact: Before disposables were invented in the 70’s, most babies in Western cultures started using a potty as soon as they could sit up. 47% of babies were out of nappies at 12 months and 83% were fully potty trained by 18 months (Douglas & Blomfield 1958).  Many similar statistics exist for other Westernised cultures such as North America and Canada. This evidence suggests that children are capable of potty training from around 18 months and that the best time to ditch nappies is between 18-30m (Brazelton 1962, Kaerts 2012, Taubman 2003, 1997, Bakker 2000, Blum 2003, Vermandel 2008, Joinson 2009, Hellstrom 2001, Barone 2009, Blum 2004, Shei-Dei Yang 2011).

The concept of “readiness” was originally proposed by a paediatrician called Terry Brazelton who developed his theory in the 1960s (Brazelton, 1962.) Whilst the ideas underpinning ‘readiness’ are good, they are not well-defined in the literature which can be confusing for parents and result in them missing key markers which may indicate the optimum time to ditch nappies (Kaerts 2012.)  Because Brazelton was later paid to endorse Pampers, many authors argue that the concept of readiness was used as a clever marketing ploy promoted by the disposable nappy companies to encourage parents to purchase their product for longer (Olson, 2016, Kachmar, 2018, Mottram, 2018.)

We know that babies are born ready to learn all sorts of things and that what they learn is largely culturally and socially dependent. The age at which they are “ready” to learn different skills also depends on the skill being learnt.  Although there are some common markers in the literature which identify the skills necessary to be independent (motors skills, a desire to use a potty, the ability to communicate needs etc), this does not stop parents starting the journey towards learning these skills before the child could accomplish them independently. After all, we approach learning other skills gradually – so why not potty skills?

Myth 3: Early potty training can damage the bladder

Fact: Regular potty voiding protects the bladder (Bakker 2000) and supports the healthy development of sphincter control from a very young age (Benjasuwantep 2013.) Potty training between 15-24 months reduces the risk of bladder and wetting problems (Joinson 2009) and improves bladder function (Hellstrom 2001.)

Remember, the bladder is a muscle so using it regularly in a conscious way strengthens it and ensures a well-functioning messaging system between the brain and the body to help develop awareness and control. Research shows that sphincter control is present from birth, and that children can learn to co-ordinate micturition (weeing) by 9 months of age (Duong et al,. 2010).

Myth 4: your child should decide when to potty train

Fact: When it comes to potty training,  experts propose that it should be done at the child’s own pace (Brazelton, 1962.) However, research shows that when parents lead the process it is completed quicker (Berk 1990) and that the risk of problems developing are reduced when parents devote time and consistent daily effort to potty training (Lane, 2006.) Children’s interest in the potty is directly related to the onset of potty training and is not an innate “readiness” (Largo, 1996.) In other words, your child will be interested in the potty if you help nurture that interest and they are capable of potty training if you teach them the necessary skills.

Taking a liberal attitude to potty training is shown to increase the risk of developing toileting problems later on and results in a delay in training completion (Bakker, 2002.) Initiating potty training after 24 months is associated with a higher risk of daytime wetting, delayed bladder control and relapse (Johnson, 2009.) In particular, postponement of potty training beyond age 3 creates social, economic and environmental problems (Kaerts 2012.)

myth 5: pull-ups help potty training

Many parents like the idea of pulls ups as a way to avoid messy accidents at the start of potty training. However, I found no clinical evidence showing them to be an effective tool. Because pull-ups feel dry when wet and in all other ways are exactly like disposable nappies, they do not help the potty training process (Rogers, 2002.) Compared to underwear, using pull-ups were shown to be less effective in developing urinary continence (Simon and Thompson, 2006.) Potty training authors such as Olson (2016) and Glowacki (2018) argue that it is confusing for children to learn the new way whilst also using the old and therefore it is better to stop using nappies completely at the beginning of potty training, including pull-ups. You can help prepare for letting go of nappies by using Nappy Cloths in your disposable nappies.

Myth 6: Children can’t be dry at night until their hormones are properly developed

Fact: Hormones at night help suppress urine production by around 50% and for the vast majority of children, these hormones work very effectively (Sureshkumar, 2009.) Research shows that children who are dry in the day are very likely to be capable of being dry at night (Largo and Stutzle, 1977.) Babies can be dry at night from 6 months if they regularly use a potty instead of a nappy (DeVries and DeVries, 1977.)

Myth 7: If you start potty training later, it will be done quicker

Fact: The average time it takes to potty train is the same whether your child is 19-24m or after 25 months (Koc, 2008.) Potty training after age 3 is shown to increase the risk of wetting and soiling problems developing (Joinson 2009, Hellstrom 2000, Bakker, 2000 & 2002, Barone 2009, Van Gool 1989, Taubman 2003.) Earlier potty training is associated with early attainment of both day and nighttime urinary continence and is not associated with bladder dysfunction (Yang 2011.) Children who begin potty training earlier ask to use the potty verbally and non-verbally much sooner (Largo 1996.)

    This is awesome. I don’t understand how it has ever become a thing that someone would believe that gentle and noncoercive EC causes constipation. Diapers can cause constipation. If I had to poop in a diaper, it would be much harder to get it out than if I went freely on a potty while squatting…I really woudn’t prefer to be smeared in poop, and might hold it in to avoid that. Babies are just tiny humans, so I cannot imagine they feel so differently…

      Thank you and yes! Its about the that these things became more commonly accepted. Thank you for your comment. Rebecca

  2. Lizzie says:

    Yes. I’ll be sharing this with my parenting group. It’s So good to share information that is so well supported with a wide range of research, so thank you for putting this together.

  3. Clare says:

    I started doing EC for poos when my daughter was about 8 or 9 months. It worked well as she regularly went after breakfast. However when I went back to work when she was 11 months I just couldn’t figure out how to keep it up. It was fine on my days off, but on the 4 days I work my daughter spends 1 day with my mum, 2 at nursery and my husband is off with her.

    I was wondering if the later potty training we see with disposables also coincides with more women or primary care givers being expected to, or needing to, work?

    • littlebunnybear says:

      HI Clare, yes it definitely does. Research shows that potty training has gotten later and later over the last 50 years. It is recognised that contributing factors to this as disposable nappy use (which makes it easier to leave it later) and also primary caregivers working in the early years of childhood. There is so much pressure on parents these days, potty training is easy to “leave till later”. Unfortunately, the research clearly shows a link between later potty training and bladder and bowel disorders. So this is something we need to work towards getting done sooner! A child who is transitioning from EC to potty training will usually benefit from a few days of focussed learning, this could be over a weekend or short holiday. Its also important to try and make your approach consistent between caregivers, so that learning happens faster. You can find out more about my courses on the teachable website page: https://go-potty.teachable.com/courses
      All the best with your learning journey. xx Rebecca
