Many experts say you should put your spouse before your children. The theory, I believe is that, your kids will one day grow-up and leave and then you're left with your spouse... and if you've put them in the backseat for years, it may be difficult to be a couple again.
I have to admit though, that I put my son first. He's only 7 and can't take care of himself - my husband, on the other hand - is an adult and can take care of himself. So I was wondering as moms (or dads), who do you put first... your spouse or your kids?
