For a long time already the answer to this question was quite ambiguous. Is it really necessary to use such detergents as soap and shampoo during bathing babies? Recent research in this area led to the following conclusions.
Such excessive care of cleanliness for children under 2 years old can only harm. Daily use of detergents (even the most mild, that is, intended specifically for children) is one of the main causes of all kinds of skin irritations, from allergies to neurodermatitis. After all, all these funds very much dry baby's delicate skin, violating its natural protective balance.
This does not mean that you need to turn a child into a mess. Just use soap and shampoo only when the baby is really dirty or it's just time to wash your hair.
