Hi,
I had my first child at Lutheran General, but it's been 9 years, so can't comment on any upgrades that may have been made to the facilities. A couple comments. First, it is highly respected, and probably has more resources for high risk issues. Second, it is a teaching hospital. What does this mean? Well, in my case, it meant there were a bunch of student doctors running in and out of the room asking me questions and giving me bad info when I was uncomfortable and just wanted to be left alone. You can choose whether or not to have them present for the actual birth, but if not, you will have to speak up. A resident assisted the doctor at delivery, and did much of the process under his supervision. Not my choice, but I guess they have to learn somehow. All in all it seemed like a very chaotic place and I didn't like it much.
I did not have children at Alexian Brothers, but have been there for other things. Even though it is literally just down the road for me, I opted for Northwest Community Hospital instead for my other children. The primary reason is because A.B. has a policy that if anyone comes to visit, you have to put the baby in the nursery. None of your guests are actually allowed to hold the baby, just gaze at him/her through the nursery window.
I was doing some promo work and worked with the education director of Alexian Brothers & St. Alexius. Their education materials were misleading. I was initially under the impression that many classes, tours, etc. were only held at St. Alexius. In actuality, they do things at Alexian Brothers on a routine basis, and promo the special things that apparently happen more rarely at St. Alexius. So, it may be worth a call, etc. They probably have very routine tours, etc. at Alexian Brothers.
I know you didn't ask about this one, but I had very favorable experiences at Northwest Community. I've had 2 children there, and I know they've revamped the maternity wing recently. They have specialists from Children's Memorial on staff and on site in case there are any special needs.
