Something That Would Hold You Back From Breastfeeding

Liz
So I'm training a new girl at work (I work for a veterinarian) that's 6 years younger than me and she was a teen mom, had her baby at 19 (not judging by the way, I'm just giving a little background) at the end of February. Her and her boyfriend (the baby's father) is 28 and she's almost 20, they're still together. Since I'm 6 months pregnant, her and I were talking new-mommy stuff and she was saying how her baby sleeps so great. But I'm a FTM and I like to learn and take in all the knowledge and experiences that I can. I had recalled my parents had said that formula fed babies tend to sleep longer because of all the calories in formula and they stay fuller longer. So I asked if she was formula fed or if she breastfed and pumped. She said she really, reallly wanted to (breastfeed) because of how good it is for the baby. But when she was born, she tried to and she "just couldn't" because of things that happened to her in the past. I empathetically told her she didn't have to justify herself to me because not all moms can for one reason or another and that no one should judge her for her decision and not to feel guilty. When she asked if I planned on breastfeeding and I replied that I was going to, I saw she felt bad that she hadn't been.  Because I also could tell even though she's super young, she is a great mom and wants the best for her baby. But my question is, might her reason for not "being able to" be sexual abuse and would that keep someone from breastfeeding even if they physically could? (Side note: she lived with a co-worker of mine who has a daughter the same age as her, so I'm wondering if she's had some troubles in her past 😞) Again, I'm not AT ALL judging her or any really young moms for that matter, I just didn't want to pry but I was curious.
