I don't really know about schools (my daughter is 2), but I highly recommend the Birth and Women's Center. It is a freestanding birth clinic and so much more comfortable and calm than a hospital. They do complete prenatal, labor and delivery, and postpartum care. The website is www.topekabirthcenter.com
I'm also a member of a local attachment parenting group, if you're looking to meet other parents. The website for our group is www.apitopek.org
And last, but not least, if you are planning to breastfeed, Topeka has a La Leche League group that holds morning and evening meetings every month. You can look it up through www.llli.org. It's under something like 'find a group in your area'
I hope that some of this helps. Good luck on your move.
