New stay at home mom soon

So my fiancée and I talked about me being a stay at home mom a few months back and the subject came up again. He wants to work 2 jobs that pays very well and we don’t have a lot of bills. We have a 4 year old and I wanted to put my 2 week notice in until the school semester in fall and then return to work when he starts kindergarten. Now it’s not long term just until he gets into school where we don’t have to pay a weekly fee. I don’t know what it’s like and looking for advice on how to deal with being home instead of working outside the home.
