M.H.
S.,
Welcome to the area! I moved here in 2001 and I love it. I know exactly what you mean about your girls growing up too fast. Sometimes I am at once so proud and horrified at all the things my oldest can do!
Check out Newsweek's rankings of public high schools: http://www.newsweek.com/id/39380/?q=2008/rank/1 . I realize that your children are a long way off from high school, however I think the fact that there are 3 Duval County Schools in the top 100 is very telling. The students who attend these high schools also attended our elementary and middle schools. There is only one St. John's county school inthe top 100 and none from Clay County. If the schools in Clay and St. John's are so much better, then why aren't their high school students entering IB programs, taking AP tests and scoring high enough on the SAT to make the top 100. Clay and St. John's are great school districts, undoubtedly. However, saying that Duval is not is misleading.
Duval is a HUGE county. Jacksonville is the biggest city in area in the United States. We have a lot of schools with a lot of varying levels of success. You do have to research the area that you are moving to and find out about the schools. Florida gives schools letter grades based on students' FCAT scores. I believe that this is similar to what is done in Texas. You can see all Duval County Schools grades here: http://www.duvalschools.org/reseval/FSAP.asp . There are PLENTY of great schools in Duval County and I believe it is completely unneccessary to buy a home and hour or more away from Baymeadows (Orange Park or St. Johns County) in order to live in a good school zone. If you couldn't tell, I'm a teacher. My two children will attend public school in Duval County when they are of school age.
I also recommend the IntraCoastal West and Beaches area. I live in Jacksonville Beach and I love it. It is like a small town in this big city. There are a lot of kid-friendly things to do, it is laid-back, it is close to Baymeadows and the schools are great. Most of the neighborhoods are nice without having meddling homeowner's associations.
I used North Florida Obstetrics for both my pregnancies. The doctors are Dr. Green, Dr. Bing, Dr. Sievert and Dr. Morgan. I delivered at Baptist Beaches. I had wonderful pregnancies and deliveries and I wouldn't change anything.
I use Beaches Animal Clinic for our furry family members (2 dogs and 2 cats). They are wonderful. It is a practice of 3 doctors. There is very low turnover there, so many of the staff members that were there when I started going 8 years ago are the same ones now! I recently found out that my dog has cancer and when I broke down in tears in the exam room, Dr. Daniel was so kind and comforting. I will never forget that.
My children , 3 1/2 and 20 months, go to Jacksonville Beach Pediatric Care Center. It is a 24/7 Pediatrician and this has been a God-send on many occasions. My favorite person to see there is actually the nurse practioner. I do have some complaints about the practice, and I'm on a waiting list at another pediatrician's office. They aren't bad, but I'm also not OVERJOYED.
There are a few great dance studios at the Beach...Nancy Dance is the only one I can recall by name right now. We also have Kindermusic, Artoga (Art and Yoga), My Gym, Public Art Walks, Festivals, Infant Swimming Resource, Adventure Landing, the Pier, tons of parks and of course- the beach! :-) There are also lots of mother's morning out programs to choose from. Our Branch library has family storytime and I know of at least two playgroups that are specifically for this area of Jacksonville.
I also love my hairdresser, know a great real-estate agent, and have worked for a builder- let me know if you want any of that info :-)
