Here are some resources you can tap into to help you in your new area. Military onc source is a great way to find DRs, play groups and just general info about anything and it is for active duty military and their families and is free of charge!! http://www.militaryonesource.com/home.aspx?MRole=&Bra...=
Second, if you don't have your daughter signed up with her PCM yet, do so now and get a referal for a ped in the area that specialize in Turner's. You can also call Tricare and find out what they can do to help you establish a plan of care to meet her needs.
Do you have her on the EFMP yet? If not, get that done ASAP because that will also open doors for her care, child care respit for you and other things as well. It will also limit you as to where you can deploy as a family because they can only station you where your child's medical needs will be met. But that doesn't mean they can't deploy your hubby by himself! There is also ECHO that picks up where EFMP and Tricare fall behind in picking up the tab so you don't have out of pocket expenses on medical bills.
If you aren't sure where to start at your new location, try to find out who your FRG (family readiness person is) or go to the MTF (medical treatment facility) or see what info Military one source can give you.
Good luck and welcome to the south!
