How to Prepare for a Baby: The Complete Month-by-Month Checklist

Most women don’t know they’re pregnant until week 4–6, so month one is often retrospective. If you do find out early, the focus is purely on medical groundwork — nothing else matters yet.

• Take a prenatal vitamin with folic acid — start immediately if you haven’t already. Folic acid is critical in the first weeks of neural tube development
• Confirm pregnancy with your doctor — schedule a confirmation appointment to get an estimated due date and establish your pregnancy record
• Review your health insurance — understand what prenatal care is covered, who is in-network, and whether you need a referral to an OB or midwife
• Stop or adjust medications — talk to your doctor about any prescriptions or supplements you currently take
• Eliminate alcohol, raw fish, and high-mercury fish — along with other foods to avoid during pregnancy per your OB’s guidelines
• Decide who to tell and when — many couples wait until after the first trimester screening (week 12–13); others share early with close family

Morning sickness often peaks between weeks 6–9. Keep to-dos light this month — focus on the OB relationship and any early genetic testing decisions that need to be made.

• Choose your OB or midwife — ask for recommendations, check insurance coverage, and book your first prenatal appointment (usually around week 8–10)
• First prenatal appointment — includes blood work, urine test, blood pressure, weight, and confirmation of heartbeat via ultrasound
• Ask about prenatal genetic testing — NIPT (non-invasive prenatal testing) and first trimester screening are typically offered between weeks 10–14. Decide if you want these tests
• Manage morning sickness — talk to your OB if it’s severe. Vitamin B6, ginger, and small frequent meals help many women; prescription options exist for hyperemesis
• Notify HR if needed — some workplaces require early notification for benefits, FMLA planning, or schedule accommodations

The end of the first trimester is a milestone — miscarriage risk drops significantly after week 12. Most couples share their news publicly around now. Energy often returns in week 13–14.

• First trimester screening / NIPT results — review results with your OB and ask questions about any flagged findings
• Nuchal translucency ultrasound — typically performed between weeks 11–14 as part of first trimester screening
• Share your pregnancy news — if you’ve been waiting for the first trimester to pass, this is the traditional moment
• Start researching childcare options — daycare waitlists in many cities run 12–18 months. It sounds impossibly early but it isn’t. Start looking now
• Research maternity and paternity leave — understand your employer’s policy, your state’s paid leave options, and how to structure your leave application
• Begin budgeting for baby — estimate first-year costs (childcare, gear, diapers, formula if needed) and adjust your savings plan accordingly

The second trimester is widely considered the best stretch of pregnancy — energy returns, morning sickness fades, and you’re not yet in the physical discomfort of late pregnancy. This is your prime productivity window. Use it.

• Set up your Amazon Baby Registry — the earlier it exists, the more your shower guests can plan around it. Add items as you research over the coming weeks
• Second trimester blood work — quad screen or integrated screening is typically offered between weeks 15–20. Confirm with your OB
• Start planning your nursery — measure the room, decide on a theme or aesthetic, and begin researching furniture. Good cribs can take 6–10 weeks to arrive
• Research and register for a prenatal class — popular classes in your area fill fast. Look for Lamaze, HypnoBirthing, or hospital-run birth prep classes and book early
• Update your will and beneficiaries — add your child as a beneficiary to life insurance, retirement accounts, and your will if you have one
• Start a maternity wardrobe — you’ll need it now. Focus on stretchy basics: leggings, a few work-appropriate pieces, and comfortable sleep options

Month five is anchored by the anatomy scan — one of the most anticipated appointments of pregnancy. You may find out the sex of the baby if you want to know. Energy is usually still strong this month.

• Anatomy scan (20-week ultrasound) — a detailed ultrasound that checks all major organs and structures. Find out the sex if you’d like to
• Begin building out your registry — now that you may know the sex, add specific clothing, gear, and nursery items. Aim to have the registry mostly complete by week 28
• Plan the baby shower — decide on date, format, and who’s hosting. Showers are typically held around weeks 28–34. Give the host enough lead time to plan
• Research pediatricians — start interviewing pediatricians now. Many practices require a prenatal visit to get on their patient roster, and popular practices fill up
• Apply for childcare — if you identified waitlists in month 3, follow up and formally apply now
• Order nursery furniture — allow 6–10 weeks for delivery and assembly. Crib, dresser, and glider should be ordered no later than week 22–24

The final month of the second trimester. Baby is growing fast and so is your belly. Physical discomfort starts creeping in for many women — heartburn, back aches, and disrupted sleep make their first appearance.

• Glucose screening test — the 1-hour glucose challenge test is typically scheduled between weeks 24–28. This screens for gestational diabetes
• Take your prenatal class — if you booked in month 4, your class likely runs around now. Birth prep, newborn care, and breastfeeding classes are all worth attending
• Finalize your registry — aim to have a complete registry by the end of month 6 so shower invitations can go out with plenty of time for guests to shop
• Tour your birth hospital or birthing center — understand where to park, how to check in, what to bring, and what the room situation looks like
• Research cord blood banking — if you’re considering private cord blood banking, research options and sign up before birth. Decisions need to be made before your due date
• Finalize your childcare plan — confirm your daycare spot or nanny arrangement. Know your plan for the first weeks back at work

Welcome to the third trimester. Baby is gaining weight rapidly, prenatal appointments become more frequent, and the reality of impending parenthood starts to feel very real. This is a good month to start the big practical preparations.

• Baby shower — most showers happen in this window. Enjoy it, take notes on gifts received, and send thank-you notes within 2 weeks
• Review registry after the shower — cross off gifted items and identify what you still need to purchase yourself. Use your completion discount on remaining essentials
• Start assembling the nursery — get the crib built, dresser organized, and basics in place. Wash all newborn clothing and bedding before use
• Choose a pediatrician — if you haven’t locked this in yet, do it now. Schedule a prenatal visit to tour the practice and confirm they’re accepting new patients
• Prenatal appointments every 2 weeks — your OB will schedule more frequent visits through the third trimester. Keep these appointments
• Tdap vaccine — recommended between weeks 27–36 to pass immunity to baby before birth. Ask about RSV and flu vaccines as well

Month 8 is when most practical preparation should be completed. By week 35 everything important should be done — babies occasionally arrive early, and you don’t want to be scrambling at week 37.

• Write your birth plan — outline your preferences for pain management, interventions, who will be in the room, skin-to-skin contact, and cord cutting. Share it with your OB and birth partner
• Pack your hospital bag — aim to have it packed by week 35. Include items for you (ID, insurance card, toiletries, comfortable clothing), baby (going-home outfit, car seat), and your partner
• Install and inspect the car seat — have it professionally inspected at a certified check station (most fire stations offer this free). You cannot leave the hospital without it
• Pre-register at the hospital — many hospitals allow pre-registration online so you’re not filling out paperwork while in labor. Do this now
• Arrange help for the first weeks home — confirm who is coming to help, for how long, and what their role will be. Postpartum support makes a measurable difference in recovery
• Research and order postpartum recovery supplies — peri bottle, cooling pads, stool softeners, comfortable high-waisted underwear. These matter as much as anything in your hospital bag
• Set up the bassinet in your bedroom — baby will sleep in your room for the first few months per AAP guidelines. Have the sleep setup ready before birth

The final stretch. Weekly OB appointments, Braxton Hicks contractions, and the strange combination of “I am so ready” and “I am not ready at all.” At this point, the practical prep should be complete. Month 9 is for resting, connecting, and getting your mind ready for what’s coming.

• Weekly prenatal appointments — from week 36 onward, your OB will check cervical dilation, baby’s position, and monitor for signs of labor
• Group B Strep test — a routine swab test typically done around week 36. Results determine whether you’ll need antibiotics during labor
• Know your labor signs — understand the difference between Braxton Hicks and real contractions, what a bloody show means, and when to call your OB versus go directly to the hospital
• Confirm your support team — finalize who is on call for childcare of older children (if applicable), who is driving you to the hospital, and who will be in the room
• Stock the freezer — batch-cook and freeze 2–3 weeks of meals for the postpartum period. You will not have time or energy to cook in the first weeks home
• Do nothing and rest — seriously. Sleep as much as you can. Take baths. See friends. Watch things you love. The newborn phase starts soon and rest becomes a distant memory
