As your baby grows and becomes more active, his diapering needs change. Try different brands and styles to find what works best, and keep these age-by-age guidelines in mind.
Newborns: Some parents like a diaper with extra stretch that will accommodate a newborn's rapid growth. You may also want to choose a style with a U-shaped hole cut out to make cord care easier. Since newborns make small messes and get changed very frequently, absorbency isn't a huge issue.
5 to 8 months: Starting baby on solid foods means messier diapers, so a good fit with no leaks is key. Baby may be sleeping longer as well; if he soaks through his bedtime diaper, try ones designed for overnight use.
9 to 24 months: Toddlers are on the go, so look for diapers with strong tabs and plenty of stretch. Change baby often to avoid diaper rash, which can flare up when he's in motion.
24 months and up: It's potty time! Some families like disposable training pants because kids can easily take them off and they're great for accidents. Others say that kids won't use the potty if they're wearing something that feels and acts just like a diaper. Experiment to see what works for you.
