Call Dr. Sells at Intown Pediatrics on Boulevard next to the CVS across from Grant Park, her number is ###-###-####. She has been our pediatrician for 15 months and is great! I've called with a concern on a Saturday and received a call from her within 15 minutes, she is thorough and does not make you feel stupid for having those typical first time parent questions. They use laptops during the appointments and show you the growth chart and weight chart on the fly as well as print it out and give you good info to take home. I believe they also have a breastfeeding support group, if you are looking for that as well. Almost everyone in our playgroup uses her and are extremely happy. Also, not that you asked she does accept almost all insurance plans.
Congratulations on your soon to be larger family!
