Frequently Asked Questions on Medium Diapers
What age is medium diaper for baby?
Medium diapers usually fit babies between 4 and 9 months old, depending on their weight and growth. Since every baby grows at a different pace, weight is more reliable than age when choosing the right size.
What are medium-size diapers?
Medium diapers typically fit babies weighing between 16 and 28 pounds. They are designed for babies who are past the newborn stage but not yet toddlers, offering more absorbency and room for movement.
How do I know when to size up diapers?
You’ll know it’s time to size up if you notice leaks, red marks around the waist or thighs, or if the tabs don’t reach comfortably. A diaper should fit snugly but not too tight. When in doubt, moving up a size often solves the problem.
Which size diapers do babies stay in the longest?
Most babies stay in medium or size 3 diapers the longest. These sizes cover a wide weight range and fit during the busy stage of crawling and early walking. Many parents find their baby stays in this size for several months.
