There are three different parts to a disposable diaper. The part that is in contact with the baby’s bottom insulate the skin and keep it dry. The best diapers will be very absorbent (urine and stool). They allow the dampness to shift to the absorbent middle of the diaper in the middle part of the diaper. It will trap the liquid.

Thanks to Catherine, an expert in the field, I learned that the middle part of the diaper contains superabsorbent gel crystals in the form of powder. These crystals absorb dampness and expand as the urine enters. The little beads that you can sometimes feel in the diaper are what absorb the liquid after they pee. This gel is made from superabsorbent polymers which are safe for the skin, which means that there is a low chance of irritation even if petroleum-based. According to what I have read, especially in documents from the Canadian Pediatric Society, this product is not risky for the baby as long as they don’t ingest it. Not because of the composition of the product but because it expands quickly, which can obstruct their respiratory or digestive tracts which is dangerous.

The outer part of the diaper is waterproof due to the use of polyethylene or polypropylene (plastics), which keep it sealed but reduces skin breathability.

There are no diapers that can ensure zero-leaks. Leaks can occur depending on the baby’s morphology, its size and mobility. This is why we always suggest models that match the shape of your baby without being too tight.

Even if there are models for boys and girls rather than unisex, the location of the absorbent materials can vary a bit, but the difference is found in the appearance and marketing.
