The Daphne bathseat was designed with the aid of a paedtrician. It has an adjustable slide stop that enables the seat to grow with the baby. The Daphne can be used from birth until the baby sits up on thier own in the tub. As your baby is fully supported it gives you an extra pair of hands. Makes it easier to wash your baby's hair and body. Babies love it as thier head is above water and it provides freedom for them to enjoy the bath.
