How to Start Night Time Training: A Parent's Guide to Dry Nights

So, you and your little one have officially conquered daytime potty training—cue the celebration! 🎉

The diapers are mostly gone, your child is using the potty during the day, and now you're only reaching for diapers during naps and bedtime. That's a huge accomplishment (and a nice break for your diaper budget!).

Naturally, you're probably wondering:

"When should we start nighttime potty training?"

The answer may surprise you—there isn't a specific age.

Just like daytime potty training, nighttime readiness is different for every child. Some children are ready around age 2, while others may not consistently stay dry until they're 5, 6, or even older. That's completely normal. In fact, nighttime dryness is influenced by a child's physical development and parent readiness and commitment.

Instead of focusing on age, look for signs that your child is ready.

Signs Your Child May Be Ready for Nighttime Potty Training

Ask yourself these questions:

  • Do they usually wake up dry after naps?
  • Do they often wake up with a dry diaper in the morning?
  • Are they willing to drink a little less right before bed?
  • Is their daytime potty training going well? (Are they regularly asking to use the potty and having very few accidents?)
  • Are you prepared for the occasional middle-of-the-night sheet change? (Because let's be honest...there will probably be at few)

If you answered yes to all of these questions, congratulations! Your child is likely ready to begin nighttime potty training.

Gather Your Supplies

Just like daytime potty training, a little preparation goes a long way. Before you begin, have these items ready:

  • Backup sheets
  • At least two waterproof mattress protectors (or a rubber sheet, which can simply be wiped clean)
  • Extra pajamas
  • Extra underwear
  • A small nightlight if your child gets up to use the bathroom
  • A calm attitude and a sense of humor—you may need both!

Parent Tip: One of the best tricks is to layer your child’s bed like this:

Mattress → Waterproof Protector → Sheet → Waterproof Protector → Second Sheet

If an accident happens in the middle of the night, simply remove the top sheet and protector, and your bed is already made underneath. Future-you will be very thankful.

Start with Naptime First

Don't jump straight into nighttime training.

Instead, begin with naptime.

Naps are much shorter than a full night's sleep, making them the perfect opportunity for your child to practice staying dry.

Before nap time:

  • Offer fluids as usual throughout the day, but try to reduce large drinks right before the nap.
  • Don't completely cut off fluids. Your child should never feel thirsty. Simply remind them that they're not wearing a diaper for nap time and encourage them to have a smaller drink beforehand.
  • Most importantly, have your child use the potty immediately before lying down.

Emptying their bladder before sleep sets them up for success.

After the Nap

As soon as your child wakes up, take them back to the potty.

Teaching them the routine of:

  1. Potty before sleep
  2. Sleep
  3. Potty after waking

helps build healthy habits that will carry over into nighttime training.

When they are able to stay dry for at least a month then they are most likely ready to start night time training!🎉

Ready for the Next Step?

Congratulations! By introducing potty routines before and after naps, you're helping your child build the foundation for successful nighttime potty training.

Once your little one is consistently staying dry during naps, you may start wondering, "What's next?"

Transitioning from dry naps to dry nights isn't always as simple as taking away the bedtime diaper. Every child is different, and there are strategies that can make the process smoother, reduce nighttime accidents, and help your child gain confidence along the way.
