Would you be a stay at home mom if you had to give up your job forever ?

I could be a stay at home mom for a few years and then return to work. However, when I return to work I would not be able to go back to the same job. Not being able to return to the same job makes this an even harder decision right now. I’ve been at this particular job since 2008, I really like the people, my bosses, it’s a really good situation. What concerns me now is that I am worried if I don’t stay home for a few years that I will regret that I did not do that. I know they say the “days are long in the years are short” and it makes me wonder if I should just stay at home to make the most of this time with the baby. I know that nobody can decide this for me and that I have to decide myself, but just curious what everybody thinks. I do realize it is a privilege that I get to make this decision, so please know that I realize that.
