Diaper inserts/doublers make cloth diapers absorbent! There are several different types and each has its advantage and uses.
Inserts come in many different combinations of these fabrics, many different sizes, and many different thicknesses. Happy Boo is sure to have the type that works best for your baby.
Diaper Liners are not really necessary for cloth diapering, but many people believe they make diaper changes quick, easy and mess free. There are reusable liners and disposable liners.
