The size graph for newborn overnight diapers: Up to 10 lbs


As the baby grows, there are several changes taking place. The most prominent is the weight and size.

While the weight is visible, it is hard to get the size right.

Most new mothers stumble upon the changing size only when they realize that there is leakage at night. Or often when the baby is cranky, and the sleep cycle is disturbed due to frequent urination.

Sometimes the change of season is also a reason for discomfort. What’s more, it is the weight of the baby that matters, not the age. That is why a box of overnight diapers may read ‘newborns up to 10 pounds…’
