Okay... Well I'm not into either of those things but what I know a lot of women to do and what my own mother did when she had her last child who is 10 years younger than everyone else... She started a sort of at home day care. She became registered in CPR and stuff.. The certifications are pretty basic and easy. There are rules based on you're only one person and can only have so many kids under your responsibility alone and based on house size I think as well.. Things to look into. But my mom had about four kids at a time plus my little brother making 5 and she would earn a pretty nice wage from all that.her prices were of course cheaper than day cares but it really worked for her. She had the business up and running within two months after my brother was born and did that for about two years so she could stay home with him.
A little advertising online via CL or whatever else you can make a decent wage and your baby will develop better with the child influence.
