Working mom

My baby is 10 months old and I'm thinking about going back to work. We don't have health insurance, my husband has a contractor job that is commission only. And i love love love staying at home but I really want to build up our savings again (we just moved/bought a house/job transition for my husband). Both my husband and I hate the idea of daycare or someone else raising our baby but I am feeling insecure about money. My husband seems to think it isnt a big deal, but I am definitely worried. I also get concerned we don't have health insurance in case there is an emergency. I am really struggling because I do want to stay home. I also have a part time, flexible job that i work when my husband isn't working, I could take more cases/hours but feel like I am already unsupported by my husband in this job. I have talked to my husband but it is like he doesn't take me seriously. He thinks if we stick to the budget, we will be fine. But when I look at the budget, we are really pushing it. My husband is desperately trying to keep our son out of daycare, but I am just unsure about what to do. How do I i make this decision???
