If you're planning on using the kidalog diapers, these extra absorbency pads are a must! They are great for extra aborbency during overnight, and at 18 months of age, we're finding them indispensable as our little boy is putting out more "liquids" overnight, and these help prevent having to wash his sheets every morning! Be sure to pick up a good supply of them along with your kidalog diapers! You'll be glad you did!
