I purchased Maximize My SS and have tried various What If scenarios because we have a disabled adult child. The software shows that I (spouse) get a child-in-care spousal benefit. I'm confused about how that works. The SSA says this benefit stops unless I am old enough to receive benefits based on age. Page 62 of your book (Get What's Yours) says I can receive this benefit at any age. What is the rule? And could you supply the SSA link? Thanks.
