Otteroo Reviews: The Otteroo is loved (or entirely hated) by those with baths deep enough to enjoy this small wonder, a funky little neck floatie that turns your baby into a tiny human buoy. It allows full body immersion, gives babies the womb-and weightless feeling they know and love, and makes great videos for grandparents.
A separate newborn bath is also required because the Otteroo is not suitable for newborn babies. The Otteroo can only be used in a larger bathtub, which obviously necessitates you getting one of those in your home.
It can potentially be used in the swimming pool until around 35 pounds, but most babies will reject it a lot earlier than that and will outgrow the Otteroo in the bathtub by the time they are sitting independently around their half birthday.
