I breastfed my first baby for 14 months. It was hard. I had low supply. I supplemented with formula. I felt like a failure. I went to lactation consultants. I took fenugreek. I pumped around the clock. I cried over ounces.
I formula-fed my second baby from week one. Not because I couldn’t breastfeed — but because I chose not to. My mental health was suffering. My daughter was healthy. Formula was fine. I felt guilty anyway.
The guilt is the worst part. The guilt comes from both sides: from the “breast is best” advocates who make you feel like you’re poisoning your baby with formula, and from your own internal voice that says you’re not trying hard enough.
Let me tell you what the evidence actually says.
Breastfeeding has real benefits: fewer ear infections, lower risk of gastrointestinal infections, slightly lower risk of obesity later in life, maybe a small IQ benefit (though that’s confounded by socioeconomic factors). Breastfeeding also benefits the parent: lower risk of breast and ovarian cancer, faster postpartum weight loss for some, and convenience (no bottles to wash).
But the benefits are modest. A 2024 JAMA Pediatrics study compared siblings where one was breastfed and one was formula-fed. The differences in health outcomes were small — much smaller than the differences seen in studies comparing unrelated children. That’s because many of the benefits of breastfeeding are actually due to other factors: maternal education, socioeconomic status, access to healthcare. When you control for those, the benefits shrink.
Formula is a safe, complete, and regulated source of infant nutrition. Modern formula is not your grandmother’s formula. It contains iron, DHA, vitamins, and minerals. Babies who are formula-fed thrive. They grow. They develop. They bond with their parents. The idea that formula is “poison” is not just false — it’s harmful.
One of my patients, “Tessa,” had a breast reduction years before pregnancy. She knew she might not produce enough milk. After her baby was born, she tried breastfeeding. Her supply was low. Her baby lost weight. She felt terrible. She started supplementing with formula. The baby gained weight. Tessa still felt guilty — for not trying harder, for not having surgery that preserved milk ducts, for “failing.” She told me, “I know formula is fine. But I can’t stop the guilt.”
That guilt is manufactured. It comes from a culture that idealizes breastfeeding while providing no structural support: no paid parental leave, no on-site pumping rooms, no lactation consultants covered by insurance (though the ACA requires it, enforcement is spotty). It’s easier to blame individual mothers than to fix the system.
If you want to breastfeed, great. Get support. See a lactation consultant. Join a support group. But if it’s not working — if your baby isn’t gaining weight, if you’re in pain, if your mental health is suffering — formula is a lifesaver. Literally.
I had another patient, “Leah,” who combo-fed from birth. She breastfed when she was home and gave formula when she was at work. Her baby got the benefits of breastmilk without the stress of pumping. She told me, “Combo feeding saved my sanity. I don’t know why more people don’t talk about it.”
The research on combo feeding is reassuring. Even partial breastfeeding provides most of the immunological benefits. You don’t have to be all or nothing.
Here’s my bottom line: fed is best. A fed baby with a mentally healthy parent is better than a breastfed baby with a parent who is struggling, guilty, and sleep-deprived. Your baby needs you — not your milk.
If you’re formula-feeding, stop apologizing. If you’re breastfeeding, don’t judge others. If you’re combo-feeding, keep doing what works. And if you’re struggling with guilt, talk to someone. You’re not alone.
