my baby who is 25 days old has these acne type boils on his both the cheeks and few on his neck and back. what are these? is it because of hot weather or something else? what treatment should be given? any ointment or lotion?

A. Hormones in the placenta can affect how your baby's skin produces sebum. Sebum is an oily substance that the sebaceous glands in your baby's skin make to protect their skin and hair. Too much sebum can clog pores and lead to acne. In addition, babies have sensitive skin when they're born.
