Hi! I delivered both my children at Central DuPage and was extremely happy with the experiences! Once you get to the Mother/Baby Unit (post-delivery), it's more like staying in a really nice hotel than a hospital -- 100% private rooms, order your meals via room service, dessert cart comes around every evening, etc. The nurses have no problem with your decision of how much to keep your baby in the room (vs. leave in the nursery). I thought the availability of lactation consultants was excellent at CDH also (although it can get pretty busy during the "prime" feeding hours, as you can imagine!)
I strongly recommend you take a tour of each hospital before making your decision. I know CDH offers free tours for prospective parents and I'll bet Alexian Bros. does too. I took the tours very early in my pregnancy (8 weeks or so!) because it impacted the OB group I selected.
Best Wishes!!
