Embarking on the journey of parenthood comes with a myriad of choices, and one of the key decisions involves choosing the right size of cloth diapers for your growing bundle of joy. As your baby blossoms and reaches new milestones, their needs evolve, and so should your approach to diapering. In this blog post, we’ll explore four telltale signs that it’s time to upgrade your cloth diaper size.

  1. Leaks
  2. Saturated Diapers
  3. Too Tight
  4. Check the Weight Range

#1 Leaks

Leaks can be caused by an incorrect fit, but they can also be a sign that baby needs more cloth around their bum! As your child grows, so does their bladder. This means they will poop and pee in greater quantities. Baby will need the additional fabric of a larger diaper to keep up with these changes in their body. If you are encountering more pee leaks, this is an especially good sign they need more absorbing fabric.

#2 Saturated Diapers

When diapers are fully saturated you may encounter the leaks described above. If you typically change your baby every 1.5-2 hours but are suddenly finding their diapers are soaking wet within this time window, you likely need a larger diaper. Obviously the diaper is going to be wet in all situations, but if you’re finding the diaper heavy to the point of dripping after 1.5 hours you need more absorption. If the diaper seems to fit well, then you may simply need to add some extra layers for overnight. However, if there is a larger diaper size available, it is worth trying out.

#3 Too Tight

Cloth diapers are super adjustable with all the snaps on the covers. You’ll know the diaper is getting too tight when it’s leaving red indentations or seems to be cutting off circulation. Some red marks with cloth diapers are normal, like what socks leave on your ankle. But if it’s digging in too much you’ll know you need a larger diaper or to go onto the next snap adjustment.


We only carry two sizes of all-in-ones, so it’s not too big mystery when it’s time to move from the small diapers to the large ones. You’ll know it’s time to graduate from small to large when you’re at the largest snaps and the inner wings cannot lay flat when pulled back. This may look like tension and bunching in the top middle caused by the diaper being pulled too tight. When their little booty starts sticking out the back, you definitely knows it’s time for a bigger diaper!


When a prefold is too small you will notice that the corners no longer comfortable wrap all the way to the front. The snappi should not be rubbing on baby’s skin at all. If it is, you need a larger diaper

#4 Check the Weight Range

Baby’s age is not usually a helpful factor in determining their diaper size since each baby grows at their own speed. However the weight range is an essential factor. Check your baby’s weight to the according diaper size on this chart. These ranges specifically correspond to Luludew Prefolds, All-in-Ones, and Fitted Diapers.

Recognizing the right time to upgrade your cloth diaper size is crucial for both your baby’s comfort and your peace of mind. By staying attuned to these four signs you can ensure that your little one continues to experience the best in comfort and protection. Regularly assessing your baby’s needs and being responsive to these indicators will not only contribute to a happier baby but also make your cloth diapering journey smoother and more enjoyable. Remember, as your baby grows, so does the joy of parenthood, and a well-fitted cloth diaper is an essential companion on this remarkable journey.
