<prompt> Human: Well, the boys can swim. My wife and I are expecting our first child and Im trying to prepare financially for the real world. Currently, we both make a good living and are pretty good savers. However, I have no idea where to start when preparing a budget for this new lifestyle. On top of that, my wife is considering quitting her job or working part time once the baby arrives, which I fully support. My first question is on resources to use when preparing the new post-baby budget. Any recommendations on information that can help me estimate diaper and food costs, etc.? Additionally, I think I know the big ticket items I need to plan for, but a list of these would be helpful as well crib, car seat, stroller. Next, what are some costs that might increase that arent necessarily specific to the baby? Im thinking about things like massages and red wine for my wife and beer and bourbon for me... : Lastly, Im fairly familiar with a 529 for education and flex spending for childcare costs, but any other tax-advantaged programs I should be aware with the new little manwoman? Thanks a ton in advance for all of your help. Sorry if this post has already been done somewhere, but I couldnt readily find it so hopefully were all due for a refresh. Thanks!  <response>: My number one thing I tell people when budgeting is that when the baby is born heshe will be become a patient. That means you have to pay for a room and care and all of that for them and your wife. I totally did not budget for that and it was another several grand in costs that I had not planned for. Start buying diapers in various sizes over the next nine months. Use Costco or Sams usually, Amazon can compete.
