Your life will never be the same — and neither will your wallet. The expenses begin adding up as soon as you become pregnant. From the first prenatal visit to college graduation day (and beyond), there will never be another event in your life that spells financial change quite the way this one does.

Try to tackle as many of the following as possible before your baby arrives. You'll help protect both of your financial futures.

Sign up for health insurance before your baby is born

If you don't have health insurance, now's the time to sign up. If you can't get coverage through you or your partner's employer, look into plans offered by groups you may be a part of (such as a freelancers' union or small business organization), call an independent broker or look into insurance through the Affordable Care Act.

Look into the cost of prenatal services

Find out what your health insurance does and doesn't cover, like screening tests, labor and delivery options, alternative therapies, doulas and prenatal vitamins. If you can, give yourself enough time to switch insurance plans if you need better coverage.

Research your workplace's family leave policy

A large majority of American workers don't have access to paid family leave. Do the math now: Will you need to take unpaid leave and how will it affect your finances? Can you save up now to make it possible?

Find financial aid for you and your baby

Look into any special programs you might qualify for, like the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) and Medicaid. Some offer grants and scholarships specifically for single moms

Purchase life insurance and disability insurance

If something should happen to you or your partner, you'll want your child to be financially secure. A life insurance policy can help cover childcare, cleaning, cooking and more if you or your partner pass away.

If you don't already have disability insurance, you probably won't be able to get it once you're pregnant — but your partner can. And since your partner's paycheck is more important than ever now, make sure that he or she has both short- and long-term disability coverage.

Check in on your financial accounts

In addition to purchasing life insurance, you'll also want to review the beneficiaries on any 401k and retirement accounts. It'll help ensure your money goes to the right person, like a spouse or parent, in the event something should happen. 

Update (or write) your wills 

You'll need to name a guardian for this child and any future children, and make financial arrangements for them if that you and your partner aren't around. You don't need a lawyer to write a will, but it's not a bad idea to hire an estate planning lawyer to cover all of your bases.

Create a savings plan for your baby

If you haven’t started squirreling away already, how much will you put aside each month for your future child's future expenses, from preschool to college?

A 529 plan or Coverdell education savings account (ESA) can help defray big tuition costs that may come down the road.

Do a thorough, realistic budget assessment

Determine what kind of home you can afford if you'll need more space once the baby arrives (Slightly-less-tiny apartment? Cozy cottage? Expansive house?), what baby gear you'll want (top-of-the-line designer duds or hand-me-downs from your sister?) and what kind of child care you'll need.

Practice living on your new family budget before the baby actually arrives, and sock away what you're able to save.

Borrow maternity clothes 

You'll only need them for a limited time, so ask yourself if you need to purchase your maternity clothes new or if you can borrow some. Can you shop at secondhand stores or adapt non-maternity clothes for pregnancy?

Buy baby gear secondhand

If you plan to borrow or buy used gear, make sure everything checks out with current safety standards. Most clothes, toys and baby bathtubs are fine to reuse, but you may want to invest in a new car seat or your own breast pump.
