Maybe for your older kids, I don't know how many kids you have, but maybe have each child choose something that they want to do with mom, and at least for starters, only have one on one time with one kid each day and rotate through the week. Maybe have the other kids all spend quiet/reading time in their rooms or something while you spend special time with one of the kids.
I don't know how well this will work with you, my two kids are little both under 4 so, let me know what you think!
HTHs!
