It sounds to me like your baby may be outgrowing the absorbency level of the size 3. You see, the weight ranges on our packages are only a guide. A child's age, mobility, and eating habit also play a part in when leaks happen. Each time you move up in size, the diapers get more absorbent. Hope you'll move your baby up to the next size, because we know your baby’s comfort is most important!! Hope this helps!

We're so sorry to hear your little one has been experiencing leaks, and would like to help. Size and fit are a huge part of finding the right diaper for your baby. As you know, babies come in all different shapes and sizes so diapers fit every baby differently. Our diaper sizes are organized by weight, and since no two babies are the same shape you will notice some overlap between sizes. In most cases, your baby should be within the weight range for the size you are using. So we can help you further, please give us a call at (888) 665-3257.
