Large (7-14kgs)

The 7–14kg nappy stage covers one of the most exciting and exhausting chapters of your baby's first years from the first crawling adventures and pulling up to stand, through to confident walking and the early toddler years. Crawler nappies and toddler nappies need to do something very different from a newborn nappy they need to stretch, flex, contain, and stay put through constant movement, squatting, climbing, and a toddler who has absolutely no intention of lying still for a nappy change

Crawler Nappies vs Toddler Nappies: What's the Difference?

At the 7–14kg weight range, your baby will typically move through two nappy sizes and their developmental stage changes significantly across this range:

Crawler nappies (size 3 — approximately 7–11kg)
The crawler stage is when nappy demands shift significantly. Your baby is crawling, pulling to stand, cruising along furniture, and may be taking first steps all of which puts very different demands on a nappy than the more stationary early baby months. Crawler nappies need to fit securely around active legs and a constantly moving bottom, maintain leak protection through all positions, and stay comfortable through long active play sessions

Toddler nappies (size 4 — approximately 9–14kg)
By the time your baby reaches the toddler nappy stage, they are walking, running, squatting to pick things up, and exploring the world with impressive energy. Toddler nappies need maximum flexibility, a secure waistband that stays put through all movement, and comfortable leg openings that don't restrict the wide leg movements of walking and running. At this stage, many families also begin thinking about eco nappies as a meaningful step toward reducing the environmental footprint of the toddler years

What to Look for in Crawler & Toddler Nappies

Stretch and flexibility — the single most important feature of a crawler or toddler nappy is its ability to move with your baby. Look for nappies with stretchy, flexible side panels, soft waistbands with good recovery, and leg cuffs that flex through squatting, crawling, and walking without gapping or leaving marks

Secure fit through movement — a toddler nappy that shifts during active play leads to leaks and discomfort. The waistband and tabs should maintain a secure, consistent fit through all the positions and movements of the crawler and toddler stages including the very particular challenge of a toddler who is determined not to cooperate during a nappy change

Reliable leak protection — active crawlers and toddlers spend time in every possible position on all fours, squatting, sitting, standing, running. Your nappy needs to contain reliably in all of them. Look for crawler and toddler nappies with well-designed leg cuffs that sit snugly in every position without cutting in

Overnight capacity — many babies and toddlers in the 7–14kg range are sleeping through longer stretches overnight. A toddler nappy that absorbs reliably through the night without leaking or causing discomfort is essential for protecting overnight sleep for both your toddler and yourself

Eco credentials — the crawler and toddler nappy stage is one of the longest in the nappy journey potentially covering 12–18 months of daily nappy use. This is the stage where switching to eco nappies like Ecoriginals has the most cumulative environmental impact. At 5–6 nappy changes per day across 12–18 months, the difference between conventional and plant-based biodegradable nappies adds up to thousands of nappies diverting from landfill

Pull-up option — as your toddler approaches the later end of this weight range and potty training begins to feel like a realistic horizon, pull-up toddler nappies can be a useful transition tool easier to pull up and down independently and less disruptive to the growing sense of autonomy that toddlers develop at this stage

How Many Crawler & Toddler Nappies Do I Need?

Babies and toddlers in the 7–14kg nappy stage typically go through 5–7 nappy changes per day. Here's a practical stocking guide:

Weekly usage: approximately 35–49 nappies per week. Recommended stock: 2–3 packs at a time enough to avoid running low without over-investing in a single size as your toddler approaches potty training age

Overnight tip: if your toddler is a heavy overnight wetter, consider keeping one size up for overnight use the additional capacity of a larger nappy can make the difference between a dry morning and an early wake-up call

When to move up: move up to the next size when your toddler approaches the upper weight limit for their current nappy, when you notice red marks around the legs or waist, or when the nappy begins to leak despite being correctly fastened

Thinking About Potty Training?

If your toddler is in the size 4 nappy range and approaching 2–3 years of age, potty training may be on the horizon. Here are a few signs your toddler might be ready to start:

• Staying dry for 1–2 hours at a time during the day
• Showing awareness of when they are wet or soiled
• Expressing interest in the toilet or potty
• Being able to follow simple instructions
• Showing a desire for independence and wanting to do things themselves
