Tips & advice for being a SAHM

I'm having some trouble coming to terms with being a SAHM when my baby comes in a few months. Not because I don't want to stay home with my son, there is nothing I want more. I am stressed out about what happens after financially and to my family. My husband does not want to do day care and I respect it and agree and daycare isn't affordable for us anyways so that's that. Lately I get comments such as "I was never lucky enough to stay home, your husband must make alot of money" not true and "isn'tthat basically quitting?"

My own mother was a SAHM, she didn't want to be a SAHM she just didn't want to work (by 8 I was doing my own laundry and cooking for myself and my friends parents would take me to school because "she isn't a taxi", she would just pop pills and lock herself in her room ALL day and would only leave the house to shop and eventually accumulated over $20,000 of credit card debt). My parents fought constantly and divorced when I was 6 and my single dad worked his butt off to support us and pay child support but couldn't be around much.

Anyways I have no intention to be like my mom was, I plan to play with my son, take care of him and be there for him as much as possible while keeping us in a strict budget. I just worry about the financial strain it could have on us and if we will have the same fights and arguments as my own parents and even have doubta thats I will be a good parent myself sometimes because It's not like I have a good motherly reference but I wanna give this my all.

Did you have a difficult adjustment period? Did everything work out? Is there anything you recommend doing or not doing to help stay afloat in the lean times financially?
