Small (3-6kgs)

Size 1 nappies are the starting point for most Australian newborns suitable from birth and covering the early newborn weeks right through to approximately 3–4 months for an average-weight baby. Whether you're preparing your nursery before your due date, stocking up for a newborn, or finding that your baby is settling comfortably in size 1 as they grow  Baby Central has the right nappy for every change

Size 1 Nappies: From Birth Through the Early Months

Size 1 nappies are suitable from birth for most Australian newborns making them the first baby nappy most families will use from the moment they bring their baby home

For full-term babies born at an average weight of 3–3.5kg, size 1 nappies are the right starting point from day one. Unlike preemie nappies which are designed for babies under approximately 2.5–3kg, size 1 nappies are sized to fit a standard newborn body and grow with your baby through the early months up to approximately 6kg

This means size 1 nappies cover one of the most nappy-intensive periods of your baby's life — newborns typically need 8–12 nappy changes per day in the first weeks, gradually reducing to 6–8 changes per day as they grow. A reliable, soft, well-fitting size 1 nappy from a trusted brand is one of the most important practical investments you'll make before your baby arrives

What to Look for in a Size 1 Newborn Nappy

Newborn skin is delicate, thin, and significantly more sensitive to irritation than older baby skin. A quality size 1 newborn nappy needs to tick several important boxes:

Ultra-soft inner lining — the inner surface of your baby's nappy is in contact with their most sensitive skin for many hours a day. Look for newborn nappies with a soft, breathable inner lining free from rough textures, harsh chemicals, fragrances, and chlorine bleaching that could irritate delicate newborn skin

Reliable newborn absorbency — newborns feed frequently and produce frequent wet and soiled nappies accordingly. A quality size 1 nappy should absorb quickly, lock moisture away from your baby's skin, and maintain dryness between changes to protect against nappy rash in these early weeks

Umbilical cord cutout or foldable waistband — in the first 1–2 weeks before the umbilical cord stump falls away, a newborn nappy with a cord cutout or a waistband that can be folded down helps keep the nappy below the stump, avoiding irritation and supporting healthy healing

Secure, gentle leg cuffs — leaks are the enemy of every new parent's sleep-deprived life. A well-designed size 1 nappy features snug, soft leg cuffs that contain without leaving marks on fragile newborn skin

Adjustable tab fastening — newborn bodies change rapidly in the first weeks. Look for size 1 nappies with repositionable adhesive tabs that allow fine adjustment for a secure, comfortable fit as your baby grows

Freedom of movement — even in the newborn stage, your baby needs to kick, stretch, and move their legs freely. A good size 1 nappy is soft and flexible enough to allow full range of movement without bunching or restricting

How Many Size 1 Nappies Do I Need?

One of the most common questions from Australian parents preparing for a newborn is how many size 1 nappies to have ready before baby arrives. Here's a practical guide:

Newborn stage (0–4 weeks):
Newborns typically go through 8–12 nappy changes per day. In the first month alone you can expect to use 240–360 nappies. Having 3–4 packs of size 1 nappies ready before your due date is a sensible starting point — enough to get you through the first 2–3 weeks without a supermarket run on day three

Early baby stage (1–3 months):
As feeding becomes more established, nappy changes typically reduce to 6–8 per day. You'll still go through size 1 nappies quickly stock 2–3 packs at a time to avoid running out without over-investing in a single size

When to move up to size 2:
Move up from size 1 to size 2 nappies when your baby approaches 6kg, when you notice red marks around the legs or waist after removing the nappy, or when the nappy starts leaking despite being correctly fastened. When in doubt, go up a size

Important note: Don't over-stock any single nappy size before your baby arrives. Every baby grows at a different rate some spend several months comfortably in size 1, while others move on sooner. Stock 2–3 packs at a time and reassess fit regularly

Nappy Rash Prevention in the Newborn Stage

The newborn and early baby stage is one of the highest-risk periods for nappy rash simply because of the sheer frequency of nappy changes and the sensitivity of newborn skin. Here are the most effective prevention strategies for Australian parents:

Change frequently — change your baby's nappy every 2–3 hours during the day, and always immediately after soiling. Prolonged contact with moisture is the primary cause of nappy rash

Clean thoroughly at every change — use soft, fragrance-free wipes or warm water and cotton pads to clean your baby's skin thoroughly at every nappy change. Pat dry gently rather than rubbing

Allow air time — where safe and practical, give your baby some nappy-free time each day. Even 10–15 minutes of air exposure helps maintain skin health and reduces the cumulative effect of prolonged nappy wear on delicate skin

Apply barrier cream — a thin layer of zinc-based barrier cream at each change creates a protective barrier between your baby's skin and moisture. Apply sparingly to avoid affecting the nappy's absorbency

Choose a soft, skin-safe nappy — the materials in your baby's nappy are in contact with their skin for many hours every day. Both Moomin Baby and Marquise size 1 nappies are selected for their soft, skin-friendly materials an important foundation for nappy rash prevention from day one
