Make sure you have everything you need before you start – towel, washcloth, baby soap, baby shampoo, waterproof baby toys, diaper, change of clothes. If you need to walk away for any reason, take the baby with you.
If you have more than one baby, wash them one at a time. Put the other baby (or babies) in a baby seat nearby so that you can reach them when needed. Have a baby seat ready for the baby you are bathing.
