Second Trimester: What to Expect (How Dads Help)
The second trimester runs from about week 14 to week 27 of pregnancy, and for many couples it's the easiest stretch: nausea often eases, energy tends to return, and the pregnancy starts to feel real. It's also when a dad can shift from worried bystander to active partner. Here's what to expect, question by question, with one thing you can do for each.
Every pregnancy is different, so treat this as a general guide and defer to your partner's provider for anything specific to her.
Will her energy come back?
Often, yes. Many women feel noticeably better in the second trimester as the early-pregnancy exhaustion and morning sickness fade. Some don't, and that's normal too.
How you help: Don't treat the good days as a signal to stop pitching in. Use the energy window to get the big jobs done together: setting up a budget, touring daycares, planning leave. If you took on extra chores during the first trimester, keep a fair share going rather than handing them all back. Our guide to supporting your partner in the first trimester covers how that stretch usually goes.
What happens at the anatomy scan?
The detailed anatomy ultrasound is typically scheduled around weeks 18 to 22. The sonographer checks the baby's growth and the development of the organs and body structures, and many couples choose to learn the baby's sex if they want to know.
How you help: Go to the appointment. Write down questions beforehand with your partner. Because this scan can occasionally surface something that needs follow-up, be ready to listen first and react second. If the news is good, enjoy it. If it's not, your calm presence matters more than any answer you have.
When will the bump show?
Timing varies widely. First pregnancies often show later, and body type, posture and the baby's position all play a part. Around this stage many women also notice skin changes, back aches, round ligament pain and swelling.
How you help: Skip the comments about size, in either direction. Offer a back rub, take over the tasks that involve lifting or bending, and be the person who says she looks great and means it.
When will we feel the baby move?
Many first-time mothers notice the first flutters, often called quickening, somewhere in the middle of the second trimester, and it can be a bit later for some. Partners can usually feel kicks from outside a few weeks after mom does, though it depends on the baby's position and the placenta.
How you help: Take a few quiet minutes each evening with a hand on her belly, and talk or read to the baby. It's a simple way to start bonding before birth.
What appointments and tests come up?
Typical items in this window include the anatomy scan, routine prenatal visits, and glucose screening for gestational diabetes, which is commonly done between weeks 24 and 28. Your partner's provider will set the actual schedule.
How you help: Keep a shared calendar of appointments and know where the paperwork is. Our hospital bag checklist built for dads is a good project to start in this window.
What should we be doing to get ready?
The second trimester is the best time to do things that will be harder later:
- Money: Start a real baby budget and review insurance and leave options.
- Childcare: Join waitlists early if you plan to use daycare.
- Home: Plan the nursery space and any babyproofing you can start on.
- Classes: Sign up for childbirth and newborn-care classes before the third trimester fills the calendar.
- Conversations: Talk about birth preferences, visitors and who does what in the first weeks.
What are the signs to call the provider?
Contact her provider promptly for anything that worries you, and especially for vaginal bleeding, severe or persistent abdominal pain, a sudden severe headache or vision changes, sudden swelling of the face or hands, fluid leaking, or a marked drop in the baby's movements once they're established. When in doubt, call.
