"Your kids" will surely remember you, and likely be relieved
to have you back. Kid's, even special needs ones, are able
to understand far more than we give them credit for. Might I
suggest you tell them all what you have been through and
what your concerns are for them?
Let them give you feed back and listen. I think you will be
pleasantly surprised. You're going to do great, and I strongly
suspect some of your biggest support will come from the kids
you are so dedicated to.
