I started using cloth diapers when my second child was born. I really like the overall concept of the bumGenius 3.0 One Size Cloth Diapers. Cloth diapering is a significant upfront investment and it was important to me to try to save money in the long run. I like that the bumGenius 3.0 One Size Cloth Diapers grow with your baby. There are a few different options for where to snap these diapers with the goal being that these diapers grow with your baby. The smallest snap setting is idea for babies up to around 18 pounds. These diapers fit infants perfectly. The second setting worked well for my baby from 18 to around 28 pounds. The last setting is designed for babies that are 28 pounds and heavier. The diaper works very well on the first two settings. In my experience, the diaper has not worked well on the last setting. My baby thinned out quite a bit once he started walking and these diapers had significant leaks the more he started moving. I would recommend this cloth diaper for the earlier baby stages but not when your baby starts moving around. This product did not fully my goal of growing with my baby.
