Look for the telltale signs

It’s inevitable-sooner or later, you’re going to have to size up your baby’s diapers. Maybe your little one has been filling up his current diapers faster than usual, or maybe you’re just running out of diapers and need to size up. Whatever the reason, it’s important to know how to tell when it’s time to size up diapers. Here are a few things to look for.

Check for leaks

Wet or soiled diapers are not the only way to tell if it’s time for a size up — you can also keep an eye out for leaks. If you notice leaks around the legs or waist, it may be time to go up a size. Also, take a look at how much your baby is wetting each diaper. If they are filling it up faster than usual, it could be a sign that they need more absorption capacity, which a larger size can provide.

Check for red marks

Red marks on your baby’s legs or bottom can be a sign that the diaper is too tight. If you notice redness, try loosening the diaper’s waistband or tabs. If the diaper is already loose, try sizing up to the next larger size. If you’re using cloth diapers, make sure you’re not using ones that are too small—you should be able to fit two fingers between the leg openings and your baby’s skin.

Check for blowouts

One way to know for sure if it’s time to start shopping for bigger diapers is by looking for blowouts. A blowout is when stool leaks out of the diaper, overcoming the absorbency capabilities. If you find that your baby has a blowout more than once a week, it’s probably time adjust the size of the diaper.

If in doubt, size up

It’s better to size up in diapers rather than size down. When in doubt, always go with the bigger size. This is because a diaper that is too small will leak, and a diaper that is too big will just be a little uncomfortable. It’s better to be safe than sorry, so always go with the bigger size when in doubt.

Buy the next size up

It’s always better to buy the next size up if you’re unsure which size to get. Diapers are designed to fit snugly around your baby, so if the diaper is too small, it will be uncomfortable and could leak. If you buy a size too large, the diaper will be bulky but ultimately it will still do its job.

Use a diaper doubler

If you’re unsure whether your baby needs to move up a diaper size, it’s always best to err on the side of caution and size up. One way to extend the life of a too-small diaper is to use a diaper doubler. This is an absorbent pad that you place inside the diaper to increase its capacity. Another option is to layer two diapers, using one as a liner. This can be especially helpful if your baby tends to sleep for long periods at night and you want to avoid leaks.

Use a swim diaper

If your child is potty trained and accident-free during the day but still wets the bed at night, you may just need a little extra protection for those nighttime accidents. A swim diaper is a great solution for kids who wet the bed. They are comfortable, absorbent and will prevent any leaks.
