If you’re wondering what size nappies to take to the hospital or birthing centre in your hospital bag, keep in mind that a newborn baby doesn’t necessarily need a size 0 nappy. Depending on your baby’s birth weight, it’s possible a larger size will be the best fit, so take a few of each of the smaller sizes of newborn nappies to try. 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

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. 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.

To help you decide which is best for your baby at each stage of development, use our useful nappy size chart.

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.As your baby grows, he or she will have different nappy needs. This is why not all nappy types are available in all sizes. For example, the nappy types designed with more active babies in mind start at size 3 or size 4 as your baby will likely be far more active as he grows.
