But it's her money, not his. There are lots of cases of loaded parents who make bad decisions or end up with less than they thought they'd have. Others are "unreliable" and make last-minute decisions to disown their kids and to give their money to charity or to their dogs. Others remarry and then die, leaving their money to their new spouse. There are a million ways that things end up differently than the kids may have thought.
And even if everything goes "right" for the DH, OP doesn't sound comfortable sitting around, waiting for the old lady to either die or dole out a little money to them. What an awful way to live! If OP and her DH save money, the worst that can happen is that they end up with too much money!
(By the way, OP, if you do end up with "too much money," I hope you and your DH will be able to break the cycle of financial dependence with your own kids. Not that you shouldn't share the wealth with them, but clearly this particular dynamic of uncertainty is unsustainable.)
