Initially, Johnson planned to breastfeed Drew. But when her baby girl had other ideas, she fed her bottles of pumped milk. Johnson called a lactation consultant who wasn't the most supportive.

"I was like, 'Well, I bottle-fed her, because there was no way she was eating,'" she recalled telling the consultant. "And it was kind of like, 'Oh, well you've probably already ruined it. I don't think she'll go back.'"

As the 29-year-old star explained to E! News in an interview, "I just felt sad because at that point, as a mom, especially that early on, you're just trying to figure it out. You don't know anything. You don't know how to do anything. And I was trying to feed my kid and I was trying to keep her happy and make sure she was gaining weight. And to feel like I had failed her, I felt so guilty and just defeated."
