Is bathing safe for six to nine month old babies?

Yes. Baby may enjoy bath time now, splashing, cooing, and playing. Never leave your baby alone in the tub for even a minute. Genital care is often overlooked. Girls need the folds opened to clean away any buildup of creams or debris. Circumcised boys need the foreskin drawn back to expose similar buildups of body secretions or debris that can be gently washed away.
Bathing. Yes it is. Use gentle products and bathe every 2-3 times a week.
