A newborn baby shouldn’t get too dirty, so there’s no need to bathe them every day - doing so can actually dry out their skin.
As a general rule, you shouldn't bathe your baby more than 3 times per week, but you can reduce or exceed this amount if you wish - baby’s are unpredictable, after all.
When your baby gets older, they will require more bathing as they explore and play, but this should increase naturally.
