If a nappy is too big, urine and poo may run out through gaps between the nappy and the skin before the nappy can absorb it. Beyond your baby reaching a weight that’s over what’s recommended for his or her current nappy size, here are some signs your baby might be ready for a different size nappy: If you can’t comfortably fit two fingers under the waistband of the fastened nappy, it’s time for a bigger size

For example, if your baby weighs 4 or 5 kilograms a Pampers size 2 nappy might be the ideal size, but if you have a baby who is long and slim you might need to stay with the smaller of the two possible sizes (Pampers size 1) for the best fit. The leg cuffs shouldn’t have any gaps. After the nappy is on, run two fingers around just inside the leg cuffs to get them in the proper position to help prevent leaks.Most of the time, your baby's weight will fall neatly within the range of a certain nappy size, producing a good fit. In some cases, you might have a choice of two sizes, as the weight ranges can sometimes overlap. Keep your baby dry and comfortable with our selection of nappies. From new-born babies to toddlers, children and young teens, we have a range of sizes to give your little one protection from unwanted leaks.

If the fastening tapes don’t reach the centre of the waistband, it’s time for a bigger size (if the tapes overlap, the nappy may be too big)If you’re little one is in the potty-training stage than we also have some training pull-up pants that can help with that. As well as specific options for bedwetting and night-time use. Our pyjama pants use a stretchable fit like normal underwear to help children feel confident and secure from leaks. They’re super discreet as well and not easily seen underneath clothing. You may need to go up a size if you notice red marks on your baby’s tummy or thighs when you remove the nappy To weigh your baby, you can use your normal bathroom scales. Take off your baby’s clothes and nappy, and then step on the scale while holding him or her. If you don’t have scales at home or don’t feel confident about weighing your baby yourself, a health visitor at your local baby clinic will be happy to do it for you at any time. If your baby regularly gets nappy rash it may be because his or her nappies are too small and don’t hold the moisture away from the skin

Once you find the best nappy size for your little one using our nappy size chart, choosing the right nappy will be a breeze. As you know, babies come in all sizes and shapes, so nappies fit a bit differently on every baby. To keep things simpler, Pampers nappy sizes are based on baby weight – not things like age or gender. If the nappy is too small, it can leak because there isn’t enough absorbency for the volume of pee or poo We know how kids love to explore! So, our range of nappies always keeps comfort and freedom to move as priority for your young adventurer. Our inclusive range has options for bedtime, pull-up pants for potty-training, and nappies even suited for swimming!After the nappy is fastened, you should be able to fit two fingers under the waistband. This means the nappy is fitted properly — not too snug, not too loose.
