I would have ordered two lots of flowers, one for you and one for mother in law, explain to husband that your children don't want to be left out, all their friends will be doing mothers day stuff. And I would forget about making him breakfast lunch etc, spend some time with your children, making cards or cookies, and when he gets hungry suggest you go out as a family to eat. Neither of my exhusbands bothered about mothers day, so often, neither did my children, now they have children of their own they make sure they get a special day, that is how I should have been too. Don't sit back and wait, teach your children that mothers day counts
