Stay at home or not stay at home?

I am a stay at home mom of a 1 year old. I had recieved by BA a week before my daughter is born. I know there are million of stay at home moms out there, but I was wondering if it is really right for me? I am able to do it, my fiance has a decent job in the military, but is it more benifical to my daughter if I stay at home for her, or if I go out and find a job? I know it seems like a simple question, but I am a little confused about it right now.

Thanks
