Usually every 4-5 days, unless he had a blowout or something. Any more frequent and his skin dried out. As an infant. Now he gets a bath whenever he needs one. Sometimes every 2-3 days, sometimes every day. But his skin still gets dry if he has them too often.
I started daily baths at around 3 months old. Before then I did it every other day or so. Babies get stinky so easily from milk and sweat. I don’t actually use soap every time though just so that his skin doesn’t dry out. Every other bath I wash with soap, unless he really needs it.
@krystaljanae I waited to completely emerge when umbilical cord came off - then gave a full bath maybe every 2-3 days, and wipe down the other days. Like got a bucket with water a little soap, like a sponge bath.
I don't think a full bath every night for a newborn is necessary every night esep in the Winter. But that's just me 🤷🏾♀️
