Yes, Sebamed Baby Diaper Rash Cream is suitable for an 11-month-old baby. It is specially made for delicate baby skin and can be used during regular nappy changes to help protect the skin. The cream contains ingredients such as panthenol, chamomile extract, and titanium dioxide, which help soothe irritation, support skin recovery, and create a protective barrier against moisture from urine and stools. Its pH 5.5 formulation helps maintain the skin's natural balance and supports a healthy skin barrier. Apply a thin layer on clean, dry skin during diaper changes. If your baby has severe redness, swelling, broken skin, signs of infection, or the rash does not improve, consult a healthcare professional for advice.
