Baby prep checklist, trimester by trimester.

First trimester (weeks 1–13)

• Choose your prenatal care provider, if you haven't yet, and write down your questions for each visit
• Read your health insurance plan's maternity and newborn coverage
• Look up your employer's leave policy and whether you're eligible for FMLA leave (U.S.)
• Start a simple baby budget: one-time costs and monthly costs
• Decide who you'll tell, and when

Second trimester (weeks 14–27)

• Start your registry (checklist on the next page)
• Research childcare options and waitlists, if you'll need care
• Plan where the baby will sleep: a crib, bassinet or play yard that meets CPSC safety standards
• Ask your provider about childbirth and infant-care classes
• Start a name shortlist (tips on the next page)
• Write a letter to your baby (optional, and lovely later)

Third trimester (weeks 28–40)

• Install the car seat and have it checked by a certified Child Passenger Safety Technician
• Pack the hospital or birth-center bag by about week 36
• Wash a first round of baby clothes and sheets
• Choose a pediatrician and ask whether they're taking new patients
• Write down your birth preferences and talk them through with your provider
• Stock the freezer with easy meals; line up help for the first two weeks
• Check any secondhand gear against CPSC recalls

After baby arrives

• Add the baby to your health insurance within the plan's deadline (often 30 days; check yours)
• Request the birth certificate and Social Security number (usually started at the hospital)
• Book the first pediatrician visit
• Accept help. Write thank-you notes later (or never)
