If they are rashes then apply a good rash cream. I amusing mamaearth diaper rashfree cream. It is effective on other than diaper rashes also. But they are may be due to dryness in this winter season. Massage daily with a good massage oil. Apply lotion after bath everytime. You can use mamaearth body lotion, milky soft face cream and soothing massage oil. I am using mamaearth baby and mama products. All are very good natural products.
