Seventh Generation Nappies: How to Choose Nappy Sizes

How to work out nappy sizes for Seventh Generation

Seventh Generation nappies are sized by pounds rather than kilograms, which can be confusing for those of us who work better in metric!

Here's our handy guide to the Seventh Generation nappy sizes. 

Seventh Generation nappy size guide: 

Stage 1: 8 to 14 lbs / 4 to 6 kgs

Stage 2: 12 to 18 lbs / 5 to 8 kgs

Stage 3: 16 to 28 lbs / 7 to 13 kgs

Stage 4: 22 to 37 lbs / 10 to 17 kgs

Stage 5: 27 lbs plus / 12 kgs plus

Seventh Generation Training Pants size guide:

3T-4T: 32 to 40 lbs / 14.5 to 18 kgs

4T-5T: 38 lbs plus / 17 kgs plus

We do find that the Seventh Generation nappies run a little on the small side, so you're best to size up if you're not sure or if your baby is on the outer range of these nappies.

For newborns under 3kgs, Seventh Generation do have a newborn size, but it's not available in Australia. You may want to have a look at the  Bambo Nature newborn nappies instead, as these are sized from 2 to 4 kgs.

How to choose nappy sizes for baby

Why do nappy sizes overlap?

Babies come in all different shapes and sizes. Some babies have chubby thighs and fat little tummies, other babies are skinnies. Even though your baby may be in the correct weight range, the fit might not be quite right and you can end up with leaks and messes. 

Babies also eat and drink different amounts, so even babies of the same weight may need a slightly bigger, and more absorbent, nappy. 

Generally, when your baby is at the top of the weight range, it's best move up to the next size so that you get the extra absorbency. 

How do you know when to change nappy sizes? 

If the nappy is leaking, we find that it's usually because your baby is in the wrong size nappy. 

Check how the nappy is fitting on your baby. If there are red marks around your baby's tummy or thighs, or if the nappy feels a little too snug, it might be time to move up a size. If you're getting blowouts or persistent leaks, that can be another sign that it's time to move up. 

Sometimes the problem can be that the nappy is too big. If there are gaps around the legs and tummy, or the nappy is sitting too high at the front or back, you may need to try a smaller size. 

We make it easy for you to try different sizes with our  eco nappy sample packs. You can try a couple of nappies to check the fit before you commit to buying a full pack or carton.
