How often to bathe newborn

1. How often do we bathe our newborn ? Is it everyday? If everyday, how many times a day? And do we use gentle body wash @ every bathe? 2. Do we need to bathe our baby when they puke over their body/outfit or just use wet tissue/water to wipe it ? 3. When they poop, heard its advisable to wash their bum instead of always using wet tissue, for that do i need to use only water or also use a gentle body wash ? #firsttimemom #firstbaby
