I gave him his first sponge bath at about two weeks old and then he got his first bath in the tub two days ago which he's about to be a month old tomorrow.

not a full on bath but a sponge bath just ring it out really really good. I've been giving my 2 week baby boy baths every Monday and then wash his hair later in the week. he had his first bath in the hospital

Whenever you feel the baby needs it.

when the umbilical cord fell off lol.

After his cord fell off
