Hmmm...we moms sure have lots of difficult decisions to make and responsibilities to manage, don't we?! I really think this is a personal decision that no one can make for you. There are pros and cons, and you just have to weigh it all out and decide what is best for you and your family. Not much help, am I?
I have always been a working mom. My DH is also a shift worker, so I can relate to you there. There have been upsides to his schedule, because since he works 12 hour shifts, he has lots of days off, and has been able to spend lots of quality time with our DS; in fact, we never needed FT daycare because of his schedule. But, when he works, he really works, and he works a lot of OT too. So, school stuff, a sick kid, doctor/ortho appts, etc, have tended to fall on my shoulders over the years. DS is older now, so with that comes more freedom for me. My daycare costs ended long ago (yes, I assure you, they do come to an end!!) I can get my workouts in without having to make sure a parent is at home with our DS. You still have a little one, so that isn't an option for you right now. I also have one child, and you (and so many mom's here) have more children, which equals more work and time devoted to family schedules and other issues. Staying in the workforce has had upsides for me, and I think for my family too, but that's just me. One driving factor for me (and there are others), to stay working, also happens to be a side effect from the work I do. I manage a child support office, and I have seen too many women who had been SAHMs, financially devastated by an unexpected divorce. I have always felt that it is important for my DS for me to be able to support both of us in the event of a divorce, or unexpected death, significant illness, or job loss of DH's.
I guess I have no real answer, but I can definately relate to the tug at the heartstrings, and the feeling like you are being pulled in too many directions, and it is no fun!

I wonder what entertainment costs will run.
There's an expense I haven't factored in!

I guess I remember all the years I worked retail jobs, long hours and crappy pay, having my time sucked up putting my employer's needs first, etc, I can't imagine all that extra stress added on top of what I have. Taking care of 4 kids full time (and dealing with my Lupus) is enough for me.

Seriously though - I don't worry about this - at all. I trust him and our marriage vows that strongly. As a matter of fact - we have discussed when we see our friends get divorced that even if we weren't totally happy in a perfect marriage - we are both way too cheap and frugal to break into two households
