Amazedmom,
As a mom who felt strongly that my little DD should be homeschooled after the nightmare introduction to formal education for her in preschool, but who listened to everyone else and sent her to K anyway, pulled her out halfway to practically save her, homeschooled the rest of the year and 1st grade also, but sent her back to 2nd after a move to a different place, now in 3rd and struggles don't go away easily as you can tell from so many of these posts...I say, stick with your instincts to keep her home for K and go from there. If you are prone to headaches you'll get really sick with the stress that comes dealing with "the system" if it gets sticky. Vacations and summers here are so great when we are disconnected from school - phew! Have fun with your DD.
