Diaper Size chart by age
New parents are always confused about how to get everything right for their baby. A diaper is something all parents prefer for their babies, at least during the initial years of their life. Commonly, babies need a large number of diapers before their first birthday, and parents start piling up diapers even from their baby shower baby registry.
But it is a little confusing how to choose the correct diaper size for your baby. Diaper sizes depend not on age but weight. At the same time, it is impossible to understand the baby’s growth pattern or how much time the little munchkin will take to jump to the next diaper size. So, sometimes parents end up buying diapers that the baby outgrows very quickly or end up buying too large sizes for the baby and causing discomfort and accidents during diaper times.
So, if you are a new parent and want to remain informed about all the nitty-gritty of diaper size, when to upgrade the diaper size and how to select the right size diaper for your baby, you are at the right place.
Diaper Size Chart
As we have already stated, choosing the right diaper size for your baby is a difficult task. Some brands put sizes in different ways than others. On the other hand, your baby may directly start from size one even though he is on the newborn weight chart. And as you may see, there are a lot of overlapping weight categories for each diaper size.
So, it depends completely on your baby’s comfort and your decision about which size you choose. Diaper size is calculated by weight and not by age. However, many brands come with an age chart and follow a standard weight and age formula. Here is a comprehensive chart to follow before you plan to buy a baby diaper.
- Preemie: Up to 5lbs(approx 2.7 kgs) are for new-born, light or premature babies
- New-born: up to 9 lbs(approx 4-5kg) for newborn small and medium sized baby
- Size 1: 8 to 14 lbs ( approx 6-7 kg) for large newborn or children upto 3 months
- Size 2: 12-18 lbs (7-10 kgs) for toddlers of 2 to 6 months
- Size 3: 16-28 lbs( 8-12 kgs) for toddlers upto 2 years
- Size 4: 22-27 lbs(10-17 kgs) for children between age group 1 to 4 years.
- Size 5: >30lbs(13.5kgs) for babies upto 5years
- Size 6: >35lbs(upto 16kgs) for babies above 5 years to 7 years.
This size chart varies from brand to brand. In some popular brands like pampers, you will even find size 7 for elderly babies, although they are not very much available in the market.
When to start collecting Diapers?
Babies commonly wet 6 to 8 diapers per day during the first 3 to 4 months. This number comes to 4 to 6 during and after 6 months. Thus on average newborn babies need almost 2000+ diapers for the first year of their life. As they go closer towards the potty training phase, usage of diapers decreases.
To remain ready for this large number of diaper needs, we suggest parents start collecting diapers straight from the baby registry in the baby shower. If you have storage, try to collect diapers of different sizes for the growing size and weight of your baby. You can also buy subscriptions for the diapers and receive the different sizes of diapers at a specific time gap.
You can also collect gift cards and use them for buying diapers for the baby. Some brands or online platforms give you offers on buying a bulk of diapers. But if you choose the correct size for your baby’s diapers, you will end up wasting your money.
- As your baby will outgrow the newborn size very soon, just after three to four weeks, you need not pile up newborn diapers too much. The baby gains nearly 3 pounds of weight in the 1st month, while the newborn diapers are suitable for only up to 9 pounds of weight.
- Most of the diapers received as a gift are newborn diapers. On the other hand, hospitals also provide you with newborn diapers when you return home. So, you only need 2 to 3 packs(large) of diapers in newborn size.
- The size your baby will mostly need is size 1 and 2. Try to collect at least 4-5 large packs of each of these two sizes.
- If you have enough storage space, you can collect 7-8 packs of size 3 diapers. You can also collect them later or look for a subscription that will preferably give you some discounts also.
How to know if the baby’s diaper size is too small?
The answer is simple. Just be conscious about your baby’s diaper routine. Using low-size diapers may lead to not only just discomfort but serious irritation and rashes on the baby’s sensitive skin. Some simple rules will tell you that the baby has outgrown the last diaper size, and now it’s time to go to the next.
- Check if the diaper accidents are too frequent. It is common for babies to spill off or wet diapers by accident. Sometimes leakage is also common. But if you see the accidents are too often, it’s now time to go to the next tab.
- Tale a look at the waistband. If you find red marks on the baby’s skin, then the diaper is too tight for your baby. You can even put your two fingers inside the waistband. If you find it too tight, choose the next size as soon as possible. Also, check the baby’s thighs and make sure whether they fit properly or not.
- Take a look at your baby’s bottom. If it is not properly covered with the diaper, then the diaper is not fit for the baby.
- When you are trying to attach the side tabs of the diaper, make sure that they attach correctly. If it flips open or is too tight to attach, the baby is now ready to go to the next size of the diaper.
Above all, keep following the baby’s behavior. If the baby shows more irritability than usual, this may be due to a misfit of the diaper. Sometimes, it becomes a problem as the smaller size becomes too small and the above one too loose. Then you can choose some other brands of the same size category also.
What will happen if the diaper size is too big?
- Usually, too big diapers flip open or come down from the baby’s thigh area. The right size diapers should not have much space in the leg’s cuff areas.
- Some parents think that big diapers will absorb much. But on the contrary, big size diapers increase the chances of leakage too often.
Tips for choosing the right diapers for your baby
Tip1: Choose the right brand:
There are a lot of popular brands that offer almost the same quality and comfort for baby diapers. So, before you choose any brand, make sure that the size chart of the diaper matches your baby’s weight and growth rate. Pampers Cruisers, Pampers Swaddlers, Pampers Pure, Huggies Little Movers, Huggies Snug and Dry, Mumma Bear all are very popular disposable diaper brands.
Tip 02: Buy in small size:
Buying diapers in a rush or stuffing too much may not be a good idea. Your baby’s growth rate may vary anytime, so buy in a small size. It is sometimes difficult to return diapers of one size and buy another. You can use subscriptions or gift cards to buy diapers later.
Tip 03: Choose the right kind of diaper:
There are many variants of diapers available in the market. Many parents use reusable cloth diapers that, for newborns, mean 30 to 40 diapers for 2 to 3 days. But most parents prefer disposable diapers in the initial months as babies need too many diapers in those days. There are swimming diapers that come with much more absorbing power than others. Some popular diaper brands like Huggies, Pampers, Honest come with overnight diapers.
But they come only from size 3 as you know that babies start sleeping overnight only after reaching a certain age group. You may not get a size 7 overnight diaper, but Pampers Underjams diapers cover up to 58 to 68 pounds that are enough for older children too.
Tip 04:Avoid health risks:
Studies reveal that sometimes using tight diapers for too long or for the harmful dyes used in the diaper, babies often experience skin rash or discomfort. So try to choose brands that are popular and trusted by many parents.
Finding out the right diaper size for the baby is definitely a strenuous job. But as your baby’s comfort is always at the top of your priority list, we always suggest you take time to think and decide the right diaper size depending on your baby’s weight and age. You can take help from other parents too as they can also help you with their experiences.
