Grahamopened up to PEOPLEin August about being pregnant again and said “being in control” while expecting “just gets thrown out the window.”
“I learned that the hard way when I tried to control everything when I was pregnant with Isaac and I told myself that I was going to bounce right back because I was breastfeeding and everybody told me, ‘Oh, if you breastfeed you’re going to lose all the weight,’ " Graham said. “And I had a few honest women tell me you will never feel the same. So they were just blunt with me and sure enough, I haven’t felt the same.”
“And then boom. I was like, ‘Well, I just got pregnant again so maybe I’ll never feel the same and I don’t even know what I felt like before I was pregnant with Isaac anyways,’ " she added.
