Advice needed

So I earn considerably more than my husband, so it's fair to say that I am the one who pays for everything - groceries, bills, school fees, house loan, car loan, everything. Hubby is self employed, so some months he might earn some (still less than my salary) and other months, he might not earn anything.

I'm currently 37.4 weeks pregnant. I don't know if it's pregnancy hormones triggering me but I've noticed that hubby spends all his money (whatever he earns) on himself, like getting glasses made, buying books, going to the dentist to whiten his teeth, which in my view are not urgent. We need to save money for when the baby comes. Am I being fair to think that he should be saving his money for the family, for e.g emergencies or hospital fees for when I go into labour? I don't think it's fair that only I think of the family and sacrifice my needs and wants, but he doesn't do the same.
