I do not have any special needs kids myself, but both my husband and I have a special needs family member on each side of our family. (My nephew, his cousin).
But I do want to say, BIG prayers for all of you as you go through the daily struggles of your life! Your kids are all so very lucky to have you loving them, supporting them, and being there for them as you can! I think your group would be an amazing thing for you all to love and encourage each other!
