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. Unlike regular nappies that you wrap around your baby’s bottom and secure with tapes at the side, nappy pants have an all-round waistband that makes them ideal for active babies and toddlers who are less willing to lie still for a nappy change. 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 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)

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: 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. When switching from regular nappies to nappy pants, you might be wondering whether the sizing is different. Pampers nappy pants are available in sizes 3 or 4 upwards, and usually your little one is likely to need nappy pants the same size as the regular nappies you’re already using. Pull on a fresh pair of nappy pants – the soft and stretchy waistband makes it easy to pop them on, no matter how wriggly your baby is. There you go, all done!

Remember changing your first nappy? If it seemed difficult the first few times, you probably soon got the hang of it – but now you might be finding it more of a challenge again as your baby becomes more active and wriggly. If you can slip two fingers under the waistband when the nappy’s on – this means the nappy’s not too snug or too loose.
