Your situation is so similar to mine except for our dd's ages. In our case school recommended that we skip k and go to the 1-5 grade level for 1. Teacher is flexible and further accelerated dd with challenging content. We also has the option to undo the skip if at any point we felt uncomfortable. We agreed to the skip and it was the best decision. When you have a school that is so child focused and flexible, you can't go wrong, imho. I had the same concerns about sending a newly turned 5 to 1st grade but her maturity level and social skills have developed to match her classmates', and all in a good way- no unwanted growth in maturity
. So I say go for it. All the best with your decision!
