First, congratulations! It’s such an honor for me to take part in documenting such a special time in your life.
Maternity portraits usually should be taken around the 7th and 8th month depending on how big you’ve gotten and your condition during your last trimester. The Pregnancy belly is the optimum size during the 7th or 8th months for portraits.
Earlier than that, your belly may be too small unless your carrying multiples. If you’re gaining a lot of weight or carrying more than one baby, you will most likely want to do your portrait session sooner rather than later. Many women retain water and look puffy during the last month of their pregnancy.
