Although some Parents like to bath their babies every day there is no evidence to suggest this is necessary.
Overuse of cleansers and even tap water can upset the PH level in your babies delicate, developing skin.
Both Parents and babies should enjoy bathtime. Look out for gentle PH neutral cleansers and mild soaps especially designed for babies as their skins can be particularly sensitive. Always use sparingly in the first few weeks.
Washing your baby's face regularly as well as his/her genital area after a nappy change should be enough to keep him/her clean and fresh in between baths. Obviously as they get older and come into contact with more things then you may wish to bath your little one more frequently, but on average about twice a week is quite adequate to begin with.
Using a full size adult bath can be quite daunting for both Parents and their babies to begin with so use either a sink or specially designed baby bath. This will allow you to have more control over your baby's movements. As they get older and you become more confident you may prefer to use a baby support or seat for them in your own bath.
