The Newborn Premium Dry Fast is super stretchy with a wetness indicator (a smart colour-changing strip to make it clear when your baby needs changing), while the Nappy Pants' ultra-dry air system boasts even liquid distribution, fast absorption and they’re dermatologically accredited. Mumsnetters know that not all baby products are created equal. That's why we obsessively research all sorts of products, from the best changing bags to the best breast pumps and best baby bottles. It's one way we can help make parents' lives that little bit easier. How we chose our recommendations 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.

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:

Types of nappy

Nappies generally come in sizes 0 to 6, fitting babies and toddlers of weights between 1kg and 16+kg. Nappies for younger babies often prioritise keeping your baby dry. As your baby starts to crawl and toddle, nappies are often labelled as ‘active’ and aim to prevent any leaks. Dr Hillary Jones -Up to a third of babies and toddlers in nappies can have nappy rash at any one time. Most forms of nappy rash can be identified by red, sore looking spots and may feel hot to touch. In more severe cases it can resemble a ‘burn’. Whilst this reaction is uncomfortable for babies and worrying for parents, it is very common and treatable. First size, I used Pampers. After that, I used Sainsbury’s. They are as good as Pampers and less price. I found the Aldi ones too bulky but Sainsbury’s is a lot thinner" - recommended by Mumsnet user, Soubriquet Our verdict

We used the size 1 and 2 of the Boots’ own, but weren't so keen on the size 3 as they don't have a wetness indicator and didn't feel quite as padded as the smaller sized ones. We switched over to Boots’ Little Stories Bamboo nappies and also really like them" - recommended by Mumsnet user, Winglessvulture Our verdict We think Aldi’s Mamia Ultra-Dry nappies are the best nappies to buy right now. They offer great value for money, feature a range of choices to suit different households and receive overwhelmingly high praise from parents across the UK. Why you should trust us Boasting an Aldi Price Match, starting from 5p per nappy, Tesco's Fred & Flo is an excellent supermarket nappy option that our Mumsnetters rate (despite some online reviewers reporting leaks). 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. Every child is different so you’ll find your own groove. However, expect an average of 70 nappies per week for a newborn baby, 50 to 70 for a child wearing size 1 nappies, 35 to 50 for size 2 and approximately 35 for size 3. Recycling charity Wrap estimates that by the time a baby is potty trained, they could have used a total of 4,000 to 6,000 disposable nappies. What are the best nappies to buy?We carried out a thorough investigation and found there was nothing contained in the nappies that was cause for concern, and so made the decision to return them to our shelves. You can read more about that decision here (link to Lizzy blog) When it comes to their nappy routine, changing a sensitive bottom regularly can really help to minimise the amount of time the skin is exposed to the natural chemicals in wee and poo. And whilst risky to carpets – letting babies have a little nappy free time each day can be helpful.

Better for the environment as reusable and outer exterior fabric is made from 100% recycled plastic waste To help parents identify nappy rash and offer some hints and tips on how to treat it, I’ve made this short video, which you can watch here Whether you have a baby with sensitive skin, you’re searching for something more eco-friendly or you're on a tight budget, we hope this list helps you find just what you and your baby need.
