What to Do When You Feel Unsupported or Dismissed
If you've tried to have this conversation with a provider and felt brushed off, you're in very common company. Many people report being told simply to stop breastfeeding, or to 'just push through' without any real engagement with their concerns. If that has been your experience, here's what I want you to know: you have every right to push back, ask more questions, or find a different provider.
You can ask specifically: 'What evidence are you using to make this recommendation?' You can ask for a referral to a perinatal psychiatry specialist — someone whose entire practice is built around exactly these questions. (be careful about this- a true perinatal psychiatry specialist is VERY difficult to find, most are like me who see a lot of people who are breastfeeding but do not have a specific specialty or specific training beyond just experience). You can access resources like LactMed (the National Library of Medicine's database on medications and breastfeeding) to educate yourself before your next appointment. Knowledge is one of the best tools for navigating a healthcare system that doesn't always slow down enough to do this right.
Monitoring What Matters
If you and your provider decide to start medication while breastfeeding, follow-up matters. Your provider should be checking in on how you're feeling, any side effects you're experiencing, and ideally how your infant is doing — watching for any changes in feeding, sleep, or behavior, though these are generally not expected with carefully selected medications at appropriate doses.
You should feel empowered to report anything that feels off, either in yourself or in your baby. This isn't about worrying — it's about being an informed, attentive participant in your own care and your infant's wellbeing. The goal is your recovery and your baby's health together. Those goals are not in conflict. (I think that this might make people scared about seeking medication while breastfeeding. I think what you wrote in the above paragraph suffices and I would take this out)
It is also worth remembering that your mental health affects your baby in ways that go beyond direct medication exposure. A parent who is significantly depressed or anxious is less able to respond consistently and warmly to their infant's cues — and those interactions are foundational to healthy infant development. This is not a guilt trip; it is a reason to take your own wellbeing seriously as an act of care for your baby.
The postpartum period is a window of high vulnerability and also high opportunity. Getting the right support now — for you, specifically, with your specific circumstances accounted for — sets the foundation for your recovery and your family's wellbeing for a long time to come. You deserve a provider who treats that window with the urgency and care it calls for.
Please do not settle for less. You and your baby are worth the full conversation.
Your needs matter here too. That truth is worth holding onto, especially in moments when the system makes it hard to believe.
→ You Don't Have to Choose Between Your Health and Your Baby
If you've ever brought up psychiatric medication with a provider while breastfeeding and walked away with a response along the lines of 'just stop nursing if you need medication' — or worse, 'let's wait on medication until you're done breastfeeding' — I want you to know: you deserved a better conversation than that.
This is one of the most frequently mishandled topics in perinatal psychiatry. Not because the answer is always simple, but because too many providers default to blanket caution rather than taking the time to have a real, individualized discussion. The result is that people who are genuinely suffering go without treatment — not because treatment isn't appropriate, but because the conversation never happened properly.
Let's have that conversation now.
Why This Conversation Gets Avoided
The honest truth is that providers avoid this topic for a few reasons, and not all of them are about your safety. Some providers haven't kept up with the research in this area, which has grown substantially in the past fifteen years. Some are uncomfortable making recommendations in an area with any uncertainty, even when the risk-benefit calculation clearly points in one direction. Some are simply time-pressed and find it easier to give a blanket answer than to walk through the nuance.
The result is that patients get pushed toward a false choice — your mental health or your baby — when in many cases, that choice isn't actually necessary.
I also want to acknowledge something: the anxiety around this topic makes sense. The idea of any medication passing to your baby through breast milk is understandably concerning. Your instinct to protect your baby is not something to override — it's something to inform. The goal of this conversation is to give you actual information so you can make an actual decision.
What the Research Actually Tells Us
The science on psychiatric medications and breastfeeding has developed significantly. We now have meaningful data on how different medications transfer into breast milk, at what concentrations, and what the available evidence shows about infant outcomes.
What the research tells us, broadly speaking, is this: different medications transfer into breast milk at dramatically different rates. Some medications pass through very minimally — infant exposure is extremely low, and the existing data on infant outcomes is reassuring. Others transfer more readily, and in those cases, more careful consideration is appropriate.
Crucially, the evidence base is not uniform across all medications. Some have been studied more thoroughly than others. Part of what good psychiatric care involves is knowing the difference between 'we have good data on this' and 'the data here is more limited' — and being transparent with you about which is which.
Blanket statements like 'no psychiatric medications are safe while breastfeeding' are simply not accurate. Neither is the opposite extreme. The truth is more specific, and it deserves to be communicated specifically.
Factors That Affect Infant Exposure
The amount of medication that reaches a breastfed infant is influenced by multiple factors. The characteristics of the specific medication matter enormously — including its molecular weight, its protein binding, and how it's metabolized by your body. Some medications are simply much less likely to transfer in significant amounts than others.
Your dose matters, as does the timing of when you take the medication relative to when you nurse. Your infant's age matters — a full-term, healthy newborn metabolizes medications differently than a premature infant, and an older infant has a more developed system for handling trace exposures. Whether you're exclusively breastfeeding or supplementing with formula also affects the overall exposure picture.
These are the kinds of factors that go into a thoughtful individualized assessment — not a blanket rule.
The Risk Calculation: Both Sides of the Equation
Here's what often gets left out of the conversation: the risks of untreated postpartum depression and anxiety are real. They are not hypothetical, and they are not minor.
Untreated postpartum depression affects your ability to bond with your baby. It affects your energy, your attention, and your capacity to respond consistently to your infant's needs — and all of these things have documented developmental effects on babies. A parent who is significantly depressed is not functioning at the level their baby needs, regardless of whether they're breastfeeding.
Untreated postpartum anxiety carries its own toll — on your sleep, your ability to cope, your relationship with your partner, and your experience of early parenthood. Chronic anxiety is physiologically stressful, and that stress affects you and your environment.
When we weigh the risks of medication against the risks of not treating, we're comparing real risks on both sides. A treatment decision that prioritizes minimizing all medication exposure without accounting for the impact of untreated illness is not a conservative choice. It's an incomplete one.
Your Options — and Your Right to Know Them
There is rarely only one path forward. Depending on your specific situation, your provider might discuss options including starting a medication that has a strong evidence base for use during breastfeeding. Some parents choose to pump and discard milk around the time of peak medication levels in their system. Some decide to transition fully or partially to formula so treatment can proceed without concern. Some prefer to pursue non-medication approaches first, if symptoms are mild enough to make that reasonable.
All of these are legitimate choices. What's not okay is being steered into a choice without the full picture. You have the right to know what the options are, what the evidence says about each of them, and what your provider's reasoning is. A provider who tells you 'just stop breastfeeding' without walking you through that rationale is not giving you the care you deserve.
Questions Worth Asking Your Provider
If you're breastfeeding and considering psychiatric medication, here are questions that will help you get the information you need: What do we know specifically about how this medication transfers into breast milk and what the data shows about infant outcomes? What is the relative risk of my untreated symptoms for me and for my baby, compared to the known risk of this medication? Are there medications in this category that have more robust evidence supporting their use during breastfeeding? Can you consult with a pharmacist or a perinatal psychiatry specialist if you're uncertain?
A provider who engages thoughtfully with these questions is a provider you can work with. Someone who dismisses them, or who seems unfamiliar with the relevant evidence, may not have the expertise you need for this specific decision.
You can also access resources like LactMed — a free database from the National Library of Medicine that compiles current evidence on medications and breastfeeding — to educate yourself before or after your appointment.
What Good Care Looks Like Here
Good perinatal psychiatric care means treating you as a whole person, not just a vehicle for protecting your baby from medication exposure. It means accounting for both you and your baby in the risk-benefit equation. It means being honest about what we know and what we don't. It means respecting your values and your priorities while giving you the information you need to make an informed decision.
It also means regular follow-up. Whatever you decide, monitoring matters — watching how you're responding to treatment, checking in on your baby's development and wellbeing, and being willing to adjust the plan as your situation evolves.
You Don't Have to Choose Between Your Health and Your Baby
For most people in most situations, treating postpartum depression or anxiety while continuing to breastfeed is achievable with careful, informed care. You do not have to choose between your mental health and your baby's wellbeing in the majority of cases. What you do deserve is a provider who takes this seriously enough to figure out the right path for your specific situation — not one who defaults to an easy answer at the expense of your care.
Your mental health matters.
And not just for you, but for your baby and your whole family. If you've been brushed off on this topic, I hope this gives you the language and the confidence to ask better questions and expect better answers. You deserve real support.
