I bathe my 3 month old maybe twice/week. It's less scheduled and more when I think she needs it (like after a really messy diaper, getting sweaty from being out by the pool, and whatnot). My 3 year old gets a bath every day. I add chamomile flowers and essential oils to her bath to calm her after the craziness of school. It helps her unwind, transition from the school to home environment, and get cleaned up before dinner and bed. Bath time is sorts sacred around here. I use baths for myself to destress, relax sore muscles, detox, and mellow out. I believe hydrotherapy is totally valuable and simple in the home. But for tiny bodies with sensitive skin, there's no reason to dry them out (especially in the dry Brooklyn winters). Soon she's be old enough to enjoy bath time with her big sister!
