Is baby lotion and diaper cream necessary? When to use lotion & diaper cream?

Hello yes baby lotion and diaper cream are necessary. Baby lotion keeps baby's skin moisturized. To begin with you can use fragrance free lotion. You can apply the lotion once you pat dry baby after bath. Diaper rash cream or diaper balm can be used twice or thrice a day after you change diaper. this to to avoid redness or rash in the diaper area. I used Aveeno lotion to begin with for a month, later switched to Cetaphil. Diaper cream Desitin or Earthmama. Hope it helps
