The Summer Infant Three Stage Newborn to Toddler Baby Bath truly grows with your baby from Newborn to Toddler. The newborn clip-on sling snugly wraps around your newborn for a relaxed bathing experience. Once baby outgrows the newborn sling, the softly padded and contoured infant seat provides a comfortable and supportive place for your baby to lie while you bathe them. The large tub also allows a seated area with high back for your infant who is ready to sit up unassisted and wanting to splash and explore the bath tub.
