Rub-a-dub-dub what a versatile tub! It 'grows' with your baby, from newborn bath time tub to toddler tub with lots of room to sit & play. Each stage features optional calming vibrations to provide a soothing, spa-like bath for your little one. For newborns, the soft mesh sling with infant head support cradles teeny tiny ones in just the right amount of water. As baby grows, just remove the newborn sling and add the baby stopper insert. It puts baby at a gentle recline, helping to prevent slipping and sliding in the tub and making bath time less stressful for both of you. For older babies and toddlers who are ready to sit up & play, remove the baby stopper insert to reveal a big toddler tub. The Soothing River Luxury Calming Vibrations Tub fits in most sinks, with a built-in drain plug that makes it easy to drain, clean and dry. Use the hook to hang it on a shower rod or door for easy, space-saving drying and storage! And the whale scoop and bottle help to rinse the dirt and suds away!
