If you’re a first-time parent, you probably have limited experience selecting diapers for your newborn. You likely purchased some that are too small for your child’s size and didn’t realize it.
What happens when diapers are too small? There will be some signs such as blowouts or leaks, red marks along the thighs, or loose tabs.
Waiting any longer! Let’s dive into this article to figure out the signs showing that the products aren’t right for your baby.
What Happens When Diapers Are Too Small?
In general, it’s not too hard to notice a too-small diaper because you may find out one of the following signs:
Blowouts Or Leaks
One of the most evident indicators of small diapers is when your newborn constantly leaks or has blowouts.
Leaks may appear because the diaper does not fit properly or its size is insufficient to accommodate the volume of urine or poop your kid is producing currently. It results in a messy leak or even a rash explosion.
Some parents may blame the matter lies in the brand they are using. In reality, if you buy a too-small product, it can’t contain your baby’s messes, regardless of brand.
This unpleasant situation frequently occurs during nighttime, so it’s better to choose the larger one at night. For the remaining ones, try to use them throughout the day. It could also help your baby sleep for extended periods!
Red Marks
If your baby’s thighs have red marks or rash on them, it’s an indicator that the product is excessively tight.
Normally, the part around the baby’s thighs and legs usually have a certain elasticity. If it’s too snug, it may cause discomfort, rash, or red marks on your newborn’s thighs.
Moving size up is absolutely a good idea!
It’s Hard To Connect The Diaper Tabs At The Baby’s Waist.
If you find it difficult to connect the tabs at the waist of your newborn, which might be a sign of a small diaper. This product should close without requiring a lot of tugging and pulling.
What’s more, take into account its rise. A good-fitting one should sit just under your kid’s belly button. If it’s a bit low, it’s a great idea to purchase a larger one!
