When your baby graduates to a tub, you'll have plenty of choices. Many parents choose free-standing plastic tubs specifically designed for newborns. For convenience, you can use a plain plastic basin or inflatable tub that fits into your bathtub. The kitchen or bathroom sink, lined with a towel or rubber mat, will also work.
Safety is the most important consideration — not necessarily the type of tub. Gather your supplies ahead of time so that you can keep one hand on the baby at all times. If you're interrupted, take your baby with you. Never leave your baby alone in the water.
