This tub is not a safe tub. The sling does not hold the baby in place; instead it is a slide for the baby to slip further into the water. My daughter is 5 months old and loves the tub, but I can't keep her in the tub for very long as she slides down within seconds of being placed on the sling. The sling is also supposed to snap into place, and it does, but not very strong. My daughter kicks her feet in the tub, and the sling comes unsnapped and starts to slide off the back making the sling shorter, and the water near her head deeper. I end up holding her the whole time which does not allow for bathtime fun. I would not recommend this tub at all.
