Generations of mothers and fathers made do with using the sink or the tub to bathe baby. Baby bathtubs sound cool in theory, but they aren't really necessary. In fact, they're one more thing to stow, clean, sanitize and dispose of later. After your baby starts to grow, you'll look back on all the baby paraphernalia you've accumulated and regret buying most of it. Chances are the baby bathtub will be somewhere toward the top of the list.
