Which Specialist(s) Will Your Baby Need?

Of course, which or how many of our specialists you see will depend entirely on your child’s condition. You may not need to see any of our specialists, actually. But if you do, you can take comfort in knowing you have an experienced team working to give your baby the best start in life. And if you're expecting a baby with multiple abnormalities or concerns, you can feel confident in knowing that some of the best physicians around are on hand to help.

And, thanks to our award-winning, state-of-the-art electronic health record (EHR), every member of your care team can see exactly what’s going on with your care at the same time. That means information on every test and diagnosis is available quickly and from any of our locations.

Communication and Collaboration

“Too often patients are put on a conveyor belt of multiple testing and consultations, often getting discordant advice when they are already emotionally fragile. That’s not the case at Nemours. [The nurse] coordinates everything beautifully, communication and collaboration are excellent, and the busy obstetrician doesn’t need to get involved in logistics.”

Bud (Stuart) Weiner, MD, perinatologist, Nemours Children’s Hospital, Delaware
