Three “grow-with-me” stages, each with optional calming vibrations, help soothe baby. Secure fabric sling with padded headrest comforts and supports infants in just the right amount of water, giving little ones a sense of security. As baby grows, the tub “grows,” too! Just remove the newborn sling and add the “baby stopper” insert. It puts baby at a gentle recline, preventing slipping and sliding, and making bath time less stressful. When baby is ready to sit up & play, the baby stopper insert removes to reveal a tub that’s just the right size. Plug makes it easy to drain & dry; hook makes it easy to hang on a shower rod or door for easy, space-saving storage.
