C.D.
I have been really happy with The Northwestern Children's Practice:

We see Dr. Goldstein. Although we have had same-day visits with other doctors and have been very happy with all of the staff.
When my daughter was born I was really excited to breastfeed! It was a challenge - but he was always supportive. They also have a lactaction consultant (RN) who I met with and was wonderful!
There are many benefits to a group practice. Early morning walk-in clinic and same day appointments.
They will also meet with you if you would like a pre-natal visit!
Good luck!
