Many things change after you have a baby: schedules, sleep time, and sense of freedom, to name a few.

Along with a changing schedule, there are the many physical changes you’ll see. Chief among them is stretch marks. For many women, stretch marks are as much a part of having a baby as diapers and feedings.
