I raised mine too... now, I am raising 3 grandkids. They are at the sleeping stage. I've had bronchitis and been on med's... sleeping, sleeping, sleeping. Now, I am better and slept out.
Oh honey! Bless your heart. I know there are way too many parents raising their children's children. It may work out way better for the kids tho. You have to be special for taking that on.
Hope you stay healthy. For you and those kids.
