Maternity photography timing is one of those things that sounds simple until you start thinking about it.
You want the bump to be visible. You want to be comfortable enough to move and pose. You want to book before your photographer is fully booked. And you want to leave enough runway before your due date that if something comes up, there’s flexibility to adjust.
Balancing all of that — while also managing everything else that comes with pregnancy — is more complicated than most people anticipate.
This guide is designed to make it simple. Here’s exactly what to do, trimester by trimester, to ensure your maternity session happens at the right time with the right preparation.
First Trimester (Weeks 1 to 13): The Ideal Time to Start Looking
The first trimester is not the time for your maternity session — the bump isn’t visually prominent enough yet for most traditional maternity photography.
But it is an excellent time to start researching and even booking your photographer.
Here’s why early research matters: the photographers you’ll want to work with — the ones with strong portfolios, established reputations, and the specific style you’re drawn to — book up months in advance. In the Twin Cities market, established maternity photographers can fill their spring and fall calendars 3 to 4 months out.
If you wait until the second trimester to start looking, you may find that your first and second choice photographers are already unavailable for your ideal window.
What to do in the first trimester: Research photographers. Look at portfolios. Read reviews. Make a short list of who you want to work with. Reach out to your top choice and ask about availability around your expected 30 to 34 week window.
You don’t have to book formally in the first trimester if you’re not ready — but having the conversation early means you’re not starting from scratch when the timing becomes urgent.
Second Trimester (Weeks 14 to 27): The Time to Book
Weeks 14 to 20: Early Second Trimester
This is still slightly early for the session itself, but it’s an excellent time to finalize your booking.
By this point in pregnancy, most people have shared their news publicly, the risk of early complications has decreased significantly, and the reality of the pregnancy feels more settled. Booking your maternity session in early second trimester feels right for most people — it’s real enough to plan for without feeling premature.
At this stage, your photographer can hold a tentative date in your ideal window (typically 4 to 6 months away) without requiring the session to be fully confirmed. Most photographers work with expectant clients this way — a hold that becomes confirmed as your due date approaches.
Weeks 20 to 27: The Sweet Spot for Booking
If I had to name the single best time to book a maternity session, it would be here: weeks 20 to 27.
You’re solidly in the second trimester. The anatomy scan is typically complete. The pregnancy feels stable and real. And you still have plenty of time to secure the dates you want before other families with similar due dates fill the same windows.
At this stage, I can book you into a specific date in your ideal session window, send you your style guide and prep materials, and handle all the logistics so that by the time you’re 30 weeks and focused on preparing for the baby, the photography is completely handled.
For Minnesota families specifically: if your due date falls in fall — September through November — I’d encourage booking by 22 weeks. Fall is the most competitive booking season for photographers across the Twin Cities, and maternity windows in September and October fill especially quickly.
Third Trimester (Weeks 28 to 40): The Session Window — And the Late-Booking Reality
Weeks 28 to 34: Ideal Session Timing
This is when your maternity session should actually happen.
Weeks 30 to 34 are the sweet spot for most people — the bump is full and prominent, you’re still physically comfortable enough to move and pose, and the baby hasn’t yet dropped significantly.
At 28 to 30 weeks, the bump is clearly visible but sessions can feel slightly early for some people — the roundness that defines the most stunning maternity images is still developing.
At 34 to 36 weeks, the bump is at its most dramatic — but physical comfort starts to vary significantly by individual. Some people feel great at 36 weeks; others are experiencing significant back pain, swelling, or difficulty with extended periods of standing.
If you haven’t booked yet and you’re entering your third trimester, book immediately. Don’t wait for a better time. The better time was four weeks ago — but today is the second-best option.
Weeks 35 to 38: Late Booking — Still Possible, Less Flexible
At 35 to 38 weeks, late bookings are still possible but require prompt action and acceptance of reduced flexibility.
At this stage, available dates may be limited. If your preferred photographer doesn’t have an opening in the next two to three weeks, you may need to choose between a less ideal date, a different photographer, or accepting that the session may not happen before the baby arrives.
That said — reach out anyway. Cancellations happen. Last-minute openings exist. A photographer who is fully booked this week may have an opening next week.
Don’t assume it’s too late until you’ve actually asked.
Weeks 38 to 40+: The Final Window
At 38 weeks and beyond, sessions become a question of logistics and physical capability rather than ideal timing.
I’ve photographed sessions at 39 weeks. They can be beautiful. But they require the right physical conditions — a mother who is feeling reasonably well, a session that prioritizes comfort above complexity, and a photographer who can respond quickly to available dates.
If you’re here and you haven’t booked yet: reach out today. Be honest about your week of pregnancy and your physical condition. I’ll tell you honestly what’s possible.
And if it truly can’t happen before the baby arrives — please know that beautiful images of your family don’t end with the maternity window. Your newborn session will capture this transition in a different but equally meaningful way.
Minnesota-Specific Timing Considerations
Spring (March to May) Due Dates
Spring due dates mean your ideal maternity session window falls in December through March — which includes winter in Minnesota.
For outdoor sessions, December through February in Minnesota presents real weather challenges. Studio sessions are the reliable choice for this window.
If you have a spring due date and you want an outdoor session, consider whether a slightly earlier session — at 28 to 30 weeks in late fall — gives you the outdoor setting you want before winter arrives. Many clients with spring due dates choose fall outdoor maternity sessions precisely for this reason.
Summer (June to August) Due Dates
Summer due dates mean your ideal session window falls in late February through May — with prime outdoor session weather arriving in April and May.
For families who want outdoor maternity sessions, a due date in June, July, or August creates a natural alignment with the best outdoor photography weather in Minnesota. Book by 24 to 26 weeks to secure spring dates.
Fall (September to November) Due Dates
Fall due dates are the most competitive in the Twin Cities photography market.
Your ideal session window — June through August — coincides with summer, which is generally good for outdoor photography. But fall photographers are heavily booked starting in August for the fall family session rush, which means your maternity session may compete with that demand.
Book by week 18 to 20 for fall due dates. I mean this seriously. Fall maternity availability disappears faster than any other season in the Twin Cities market.
Winter (December to February) Due Dates
Winter due dates mean your ideal session window falls in late summer and fall — typically August through November.
This is actually a wonderful window for outdoor sessions in Minnesota. The late summer and fall light is extraordinary, the temperatures are comfortable, and the landscapes offer the full range of Minnesota outdoor beauty.
Book by week 22 to 24. Fall session demand means this window fills quickly even for maternity clients.
The Simple Version
If you’ve read this whole guide and you want the simple takeaway, here it is:
Book your maternity photographer as early as feels right — ideally in the second trimester, ideally by week 24.
If you’re past that window: book today, not tomorrow.
The ideal session timing is 30 to 34 weeks. Everything on either side of that is workable with the right communication and flexibility.
And the most important thing: reach out before you assume it’s too late. It almost never is — but finding out requires making the call.
Whatever trimester you’re in right now, reach out today. I’ll tell you exactly what’s possible for your timeline and help you get the right dates on the calendar. Maternity spots in spring and summer fill quickly — don’t wait.
