With babies and children, minimal is the way to go.
Newborn baby skin undergoes dramatic changes soon after birth, gradually adjusting pH and barrier function as it adapts to the outside world. Their skin is even more permeable, thinner and delicate than the skin of a 1 year old, which means it is extremely important that products applied to the skin are carefully scrutinised.
Usually, babies and children will only need a gentle body cleanser - water alone is often sufficient, with minimal use of a fragrance-free soap in the nappy area. Follow with a gentle moisturiser or balm to soothe the nappy area or any areas of redness or irritation.
