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?
