WELCOME!!!!!!!!! There's a lot of good stuff out there!
First of all, contact the Iowa School for the Deaf. Even if you're not near it, they may be able to direct you to more local services (eg regional programs, some of which are VERY good)
Iowa School for the Deaf
It may also be a good resource later on during elementary or high school. (some kids decide to do the res school route during high school. Also some families move near the deaf school so their kids can be day students) Also many deaf schools offer summer camp programs.
Second of all, get your daughter enrolled in early intervention ASAP. I'm not sure what EI is like in Iowa, but you really need to get her in Dhh specific EI, rather then generic EI for children with cognitive and physical issues. Also initially it's a good idea to go "full toolbox"
Meaning expose her to both ASL and speech. It is hard initially, but that way she'll get exposure to both languages and she can "pick" which tools she wants to use.
Yes, speech is awesome but so is sign. They both have their usefullness and their place.

First Year Free
Program for Newly Identified Families
Through the generous sponsorship of an anonymous donor, families of newly identified deaf and hard of hearing children may join ASDC for a year at no cost through First Year Free. First Year Free families receive all the benefits of ASDC membership, including The Endeavor, parent information and referral line, Lending Library, and more. If you are the parent of a newly identified deaf or hard of hearing child and wish to receive information about enrolling in First Year Free, please call ASDC at 800/942-ASDC.
Don't worry about the CI/HA debate. CIs are getting a lot more accepted in the Deaf community.
