Should I quit my job??

I HATE my job. Actually, I like the job, but not the environment at work. I feel about as welcome there as a turd in a puchbowl. I have a new baby, and would love to be a stay at home mommy, bit finances restrict this. How much crap should anyone have to stomach for a meager paycheck? Should I stick it out until something else comes along, or do I throw caution to the wind?
