I have to agree with the ladies. It's NOT easy to work when you have baby around. It's tough to get actual solid hours of straight work in with baby around.
I WAH and have also taken a baby to work before (but the babies were not newborn so I could keep them busy with coloring and such).
I would suggest that you and your DH try saving as much money as you can during your pregnancy. Maybe even work some extra shifts, get an extra job, just to save up as much as you possibly can. That way you have more time/room/money to make your transition/decision after baby is born.
Have you really taken a good hard look at all your income and expenses? Are there things you could cut temporarily to
1) save money until baby comes
2) keep costs down until you go back to work?
I have never done a budget before and I was super surprised at how much farther the money went when we did sit and right an actual budget down (not a theoretical one a real one). Then also think about how much you really want to be able to stay home for a while after baby is born. Is it worth giving up a few things that may be costing you extra?
I know it may be tough to think about while expecting (I like to be spoiled!). lol
My SIL is actually planning to stop working altogether the next time she gets pregnant (she's had a few losses). So her and her husband are currently saving like crazy for that. They also sat down together and took a really good hard look at their income and expenses. Right now they say they need about $500/month from her income to make it, but they did estimate on the higher end.
Over the course of the next few months they will see if they can drop down in some areas and try to live on her husband's income alone. This is a great idea for a couple reasons...1) it give them a realistic idea of what it will be like and if it's possible (or if it can be possible) and 2) it allows them to put anything she makes now, over and above what they really need to pay for expenses, into the savings account
Plus she knows that IF they really do "need" the $500/month from her check and they can't cut that back any more, then she knows that if she wants to stay home for a full year, then she has to save up $6k. In the mean time, she is trying to work as much as she can, while using as little of her income as possible, so they can save faster than normal.
Just some ideas.
