How do I know when it's time to switch to a new diaper size?

Your baby is always growing, but he or she will have to wear diapers until he or she is able to potty-train on his or her own. Size is just as important when choosing diapers as it is when buying everyday clothes. But how do you know when it's time to buy a bigger diaper? The easiest way to do this is to look at the values written on the diaper package.
Kokoshi offers diapers in four sizes: 2(S), 3(M), 4(L), 5(X)L. The pack always shows the size and weight of the child for which the diapers are designed. And if you have carefully studied the Kokoshi size chart, you will surely notice that there is a slight overlap in kilograms, so that going from size to size was as easy as possible.
For instance, if your baby weighs five kilograms, you can wear a size two diaper (for babies up to six kilograms). But you may be okay with the third size (for children from 5 to 10 kilograms), as the lower limit of the third size is equal to the weight of your baby. Each mommy will be able to assess which diaper is best, based on the weight and shape of her baby.
You may be surprised at how fast babies grow. Usually, by 4-5 months, the child doubles his weight, and by a year - triple. So don't be surprised if you have to switch to a new diaper size quite often.

How do you know if the diaper is the right size for your baby?
- The diaper should fit straight and without any wrinkles. The closures should be glued symmetrically and on the colored waistband on the front of the diaper. Kokoshi diapers are quite elastic and very comfortable. They kind of adjust to the curves of the baby's body and the peculiarities of his movements, taking their individual shape;
- The diaper fits snugly around the baby's tummy just below the navel, but does not cut in, squeeze or flutter. Ideally, there should be a small gap between the baby's belly and a properly fitted diaper, where an adult's index finger can easily pass;
- If the baby is a newborn with an unhealed umbilical cord, you need to be especially careful. Be careful that the diaper does not touch or rub the umbilical cord area. If the diaper sits too high and covers the umbilical cord, you need to gently button it up by covering the cord with a dry cotton pad or soft cloth, and then turn the diaper sash outward so that the umbilical cord is higher;
- The leg cuffs should fit evenly around the baby's legs and buttocks. Once the diaper is on, run two fingers along the edges to make sure the elastic bands fit snugly around the baby's legs, but do not cut into her, and the cuffs are pulled outward. Push-in cuffs are often the cause of leaks.

The most common causes of diaper leaks are
- The size is too small, causing not enough absorbent material for the volume of your baby's secretions. If your baby has reached the maximum weight that fits the size of the diaper, it's time to change the size. You can tell if a diaper is too small not only by the leakage, but also by the way it fits on your baby. A diaper that is too small will not cover the top of your baby's buttocks or sit too snugly on the baby's legs and waist, causing discomfort and redness of the skin;
- The diaper is too big for your baby. A size too big can also cause leakage. Make sure the edges fit snugly against your baby's hips and waist by placing two fingers between the edge of the diaper and your baby's body where it fits. If the diaper is too loose, leakage is guaranteed, as the baby's secretions will simply leak out past the loose-fitting diaper;
- Sometimes diapers tear along the back. The cause is also always the wrong size or loose fit. The back is more difficult to create a tight layer, and when stretched when a child twists or sits, the wrong diaper can tear.


At first glance, everything about diapers seems complicated and confusing. But it is only so it seems. Very soon you will easily understand all the intricacies of diaper changes and easily avoid leaks and rips, even without much control over it. Just get in the habit of taking extra diapers and supplies with you wherever you go with your baby.
