Are you a first time mom wondering how to purchase the right diapers for your newborn? You are in the right place. The truth is, you will need to change your newborn’s diaper about 8-10 times per day. For baby’s age 6-month-old, you will change diapers for about 5-6 times per day. In the first month of life, your newborn will probably need about 300 diapers. So, you really need to know what works for you.
But before we dive into the baby diaper buying guide, let’s do the math. (Note: These are estimated figures I gathered from different moms, it is not cast in concrete. Your own baby might use less or more.).
Babies are different, what works for me, might not work for you. So, use the calculation as an estimate only.
