Why Waiting Until 3 to Potty Train Might Make It Harder

Many parents think waiting until their child is three is the “safe” or “easier” choice. After all, older toddlers seem more capable of understanding instructions and routines. But in reality, waiting too long can actually make potty training more challenging — for both you and your child.

What Happens When You Wait Too Long

Toddlers around 18–24 months are at a stage where their bodies and brains are naturally ready to start recognising bladder and bowel sensations. By waiting until three, your child may have already developed habits that make it harder for them to want to remove the nappies and become fearful of change. 

This can lead to:

• Power struggles: Older toddlers are more aware of control and independence. They may resist potty training as a way to assert themselves.

• Longer training time: Older toddlers may take longer to fully transition because they’ve been used to nappies for years.

• Accidents and frustration: The longer the delay, the more ingrained the habit of nappies, making accidents more frequent and potentially stressful for both parent and child.
  
  

Starting Earlier Can Be Easier

Potty training at 18–24 months aligns with your child’s natural development. Toddlers are often curious, adaptable, and open to learning new routines at this age. By starting earlier, you can:

• Reduce the likelihood of battles over using the potty

• Build habits gradually and naturally

• Make the transition from nappies to underwear smoother

• Encourage independence and confidence from the start

In short, early potty training can be quicker, calmer, and less stressful — when done gently and with the right approach.

Gentle Preparation is Key

If you’re considering potty training but your toddler isn’t quite 18 months yet, there are simple things you can do to prepare them. These steps can help your child build confidence and make the process feel natural, even before the nappies comes off.
