How to find the perfect diaper size

Choosing the right diaper size for your baby can mean the difference between a good night’s sleep and changing crib sheets at 2am. And while weight ranges are a good starting point, there are a few other things to take into account to find your baby’s ideal size — at least until their next growth spurt!

Here’s a quick primer on proper diaper fit:

  • 1.

    In addition to weight, think about your baby’s age, body type (height and build), and waist circumference.

  • 2.

    Your baby’s diaper should always fit high and snug around their waist, with just enough room to slide one finger into the waistband.

  • 3.

    There shouldn’t be any gaps in the legs or waist, and the diaper tabs shouldn’t overlap.

  • 4.

    If there’s an uptick in leaks or blowouts, it’s likely time to size up. Most often, these will start to occur at night, with the culprit being a too-snug diaper.

How to tell if your baby’s poop is normal

The color of your baby’s poop is a key indicator of their health, so it’s important to know what to expect and when to check with your doctor (though, when in doubt, always check with your doctor!).

Your baby’s first bowel movement will likely happen within their first 24 hours of their life. Their first stool will likely be a green-black color that is tar-like in consistency. This is normal! What you’re seeing is called meconium and contains the amniotic fluid that your baby was exposed to in the womb. It will also likely be odorless (hurray!) as the poop is sterile since bacteria isn’t yet present in their intestines.

Your baby will go through a range of stool colors, especially as their diet changes. Breastfed babies tend to have loose stools that are yellow, green, or light brown in color.

The more you add to your baby’s diet, the more normal their stool becomes. If you ever notice that your baby’s stool is white or red, contact your doctor immediately, as this could be the sign of an underlying health issue. Also, always be sure to watch out for signs of constipation or diarrhea.

How to determine how many diapers your baby might need in a day?

Our packs are designed to last for approximately five days, which is why the quantity varies depending on the size diaper, and 6 packs should last you a month. The chart below shows approximately how many diapers your child will go through in a week (one pack) or month (one shipment) depending on their diaper size.

How frequently should I change my baby?

We recommend that you change your baby every 2-3 hours during the day, unless they need it sooner. A mostly wet diaper moves like jelly and should be changed. It’s important to know that letting your baby sit in a wet diaper for too long can lead to skin irritation and rashes (not to mention leaks!). If your baby is experiencing any diarrhea, we recommend more frequent changes because feces tend to be more irritating against a baby’s delicate skin.

At nighttime, there is no need to wake a sleeping baby so you can change their diaper. Let them sleep unless their diaper soaks through to their pajamas (unlikely if you’re in a Coterie diaper).

How to prevent diaper rash?

The best way to prevent diaper rash is to try and keep your baby’s skin as dry and clean as possible. When a baby’s bottom is exposed to a soiled diaper for a long period of time (especially a poopy diaper), the chances of a rash increase because the bacteria is sitting against their skin and breaking its protective barrier.

When cleaning your baby’s tush, make sure to clean the entire area using a gentle wipe, free from fragrances and other harsh chemicals. And don’t forget to clean their tummy and thighs too!

Another great tip to help avoid diaper rash is to try and expose your baby’s bare bottom to air, giving their skin a chance to breathe.
