Preparing for Baby In St. Louis

Each birth is unique, and so is each pregnancy.

From now until the birth of your baby, you'll have lots to consider and do - choosing the perfect name (or names!), selecting the safest car seat and preparing for childbirth (should I use a birthing ball?). Mercy will help you make this experience everything you want it to be.

As St. Louis childbirth leader, Mercy will provide the expert care, support and comfort you'll need - before, during and after your baby's birth. We know it's the little things that count for you, such as taming your morning sickness with lemon drops or helping you with baby's first feeding. There will be many "firsts" for you, such as feeling a fluttery kick, that are as unique as you are. Without one-size-fits-all thinking, our focus is on you, your Mercy birth plan and bringing your baby safely into your waiting arms.

Here at Mercy, we are honored when expectant parents choose to bring their child into the world at our hospital. Here is some helpful information as you begin your journey to parenthood.

Our Maternal and Fetal Medicine physicians (specialists in high-risk pregnancy) are available 24/7, and we offer three Maternal and Fetal Health Centers - Creve Coeur, O'Fallon and Maryville, IL - to provide you with expertise, convenience and the latest diagnostic technology closer to home. If you are diagnosed with an anomaly or illness that requires additional care, you will receive guidance from our Fetal Care Team, who will help you through the process prior to birth and assist you with the coordination of pediatric specialty care if needed after your baby arrives. Addressing health issues earlier leads to healthier newborns.
