If you’re staring at a shelf — or a browser tab — trying to work out whether to buy DryNites, a standard pull-up, or something that looks suspiciously like a nappy, you’re not alone. The naming is inconsistent, the packaging is confusing, and the products themselves vary more than most parents realise. Here’s what actually separates them.
The Three Categories: A Plain-English Breakdown
The terms “DryNites,” “pull-ups,” and “nappies” are used loosely — sometimes interchangeably — which makes comparison difficult. They refer to meaningfully different product types, each designed for a different situation.
DryNites (and equivalent branded overnight pull-ups)
DryNites is a brand name — made by Huggies — but it’s become shorthand for the whole category of purpose-labelled bedwetting pants for older children. The products are designed specifically for nighttime use, are marketed from around age 3 upwards, and come in sizes reaching up to 15+ years in some ranges. Goodnites (sold in North America) is the equivalent product.
DryNites are pull-up format — worn like underwear, pulled up and down — and are designed to be discreet enough that a child can manage them independently. Absorbency is significantly higher than daytime training pants. They are widely available in supermarkets and pharmacies.
The key limitation: they are still a consumer retail product designed around typical wetting volumes. Heavy wetters, larger children, or children who move significantly during sleep frequently find they leak. The absorbent core is positioned for an average sleep posture, which doesn’t suit every child.
Standard pull-ups (training pants and daytime pants)
Standard pull-ups — including brands like Pampers Kandoo, own-brand training pants, and similar — are primarily designed for daytime toilet training. They have pull-up format but lower absorbency, and they’re sized for toddlers and young children.
Using a daytime training pull-up for overnight bedwetting is one of the most common sources of frustration for parents. The product simply wasn’t built for it. Even a modest wetting event overnight can overwhelm a training pant’s capacity when a child is lying down, because the fluid distribution is completely different to standing up.
If your child is wetting overnight and you’re using standard training pants, switching to a dedicated overnight product — at minimum — is worth doing before anything else.
Nappies and taped briefs
At the far end of the absorbency spectrum are taped briefs — products with side tabs rather than pull-up format. These include products like Pampers (in larger sizes), Tena Slip, MoliCare Slip, and similar brands aimed at continence management.
These are often dismissed as “nappies” with the implication that they’re inappropriate for older children or teenagers. That’s an unfair characterisation. Taped briefs typically offer the highest absorbency available, better leak containment when lying in varied positions, and in many cases better comfort for heavier wetters than any pull-up can achieve.
They are harder to self-manage — a child generally needs an adult to help fasten them — which is relevant for older children who value independence. But for children with complex needs, very heavy wetting, or where containment is the primary goal, they are entirely appropriate and should not carry stigma.
How Absorbency Actually Compares
Absorbency figures are not standardised across brands, so direct comparison is difficult. However, as a rough guide:
- Daytime training pull-ups: typically 100–200ml capacity
- DryNites / overnight pull-ups: typically 300–500ml, depending on size
- Higher-capacity pull-ups (e.g., Drynites larger sizes, specialist brands): up to 600–800ml
- Taped briefs (Tena Slip, MoliCare): often 800ml–2000ml, depending on product tier
Average bladder capacity in children increases with age — roughly 30ml per year of age as a general guide, though this varies. A 7-year-old might have a functional capacity of around 200ml; a 12-year-old, considerably more. A product that works at age 5 may genuinely not be sufficient at age 10, even if the wetting frequency hasn’t changed.
For a deeper look at why products that seem adequate still leak during sleep, the issue is often positional rather than purely about capacity — the design problem with overnight pull-ups is worth understanding if you’re still getting leaks despite using an overnight-rated product.
Format: Pull-Up vs Taped — Which Matters for Whom
Format matters practically, not just symbolically.
Pull-up format suits:
- Children who manage their own nighttime routine
- Older children and teenagers who want independence and discretion
- Children who are motivated by the product feeling “like underwear”
- Situations where speed of change matters (school trips, sleepovers)
Taped format suits:
- Children with heavier wetting where pull-up capacity is genuinely insufficient
- Children with physical disabilities or complex needs where assisted changing is expected
- Situations where maximum containment overnight is the priority
- Younger children who aren’t managing their own personal care
For children with autism or sensory sensitivities, format may matter less than material and noise. Some pull-ups have crinkly, plasticky outer layers that cause real distress. Taped briefs in softer materials are sometimes better tolerated than louder pull-ups — texture and bulk are legitimate factors, not indulgence. If your child is very sensitive to what they’re wearing, this may be the deciding factor ahead of absorbency.
What Age Range Do These Products Cover?
This is where the gap in the market becomes obvious.
DryNites officially covers ages 3–4, 4–7, 8–15, and (in some markets) larger sizes beyond that. In practice, older children and teenagers are significantly underserved. The largest DryNites size is suitable for children up to around 57kg, which excludes heavier teenagers entirely.
Higher-capacity pull-ups from specialist continence brands — such as iD Pants or TENA Pants — extend coverage further, though these are not always labelled for children and can be harder to find on the high street.
Taped brief products in adult sizing cover essentially any body size, which is one practical reason they remain in use for older adolescents and young adults despite the format not being universally preferred.

Cost Differences
Cost is a real consideration for families dealing with bedwetting every night. At time of writing:
- DryNites (8–15 years, 9-pack): approximately £5–£7 retail, around 60–80p per night
- Higher-capacity specialist pull-ups: typically £1–£1.50 per unit
- Taped briefs (Tena Slip, MoliCare): typically £1–£2+ per unit at retail; can be significantly cheaper via subscription or bulk buying
In some circumstances — particularly for children with a diagnosis that includes continence issues — products may be available on NHS prescription or through continence services. If your child has been seen by a clinic, it’s worth asking specifically about product provision rather than assuming none is available.
The Honest Summary: Which Should You Choose?
There’s no universal answer — the right product depends on your child’s age, wetting volume, sleep position, sensory profile, and how much independence they want at night. But a few principles hold:
- Don’t use daytime training pants overnight. They’re built for a different purpose and will likely fail.
- DryNites are a reasonable starting point for most children up to around 10–11, and worth trying before escalating.
- If DryNites are leaking consistently, the problem is likely either capacity or core placement — a higher-capacity product or a taped brief is the logical next step, not a different brand of the same thing.
- Taped briefs are not a last resort. They’re simply a different format with different strengths. If they work better for your child, that’s the right answer.
If you’re still getting leaks despite upgrading the product, the cause is often positional — why the same pull-up leaks at night but not during the day explains the mechanics clearly. And if you’re finding the whole situation exhausting, how other parents manage night changes without burning out is worth reading alongside the product decisions.
The right product is whichever one gets your child — and you — a better night’s sleep. That’s the only metric that matters here.
