PRN work from home for extra $

I have a full time job working in an infusion clinic. I'm currently pregnant and DH and I are trying to think of ways to get a little more income to save up for my maternity leave. I don't want to do something that would take me away from home as my kids more than I already am. Is there anything out there that would be flexible hours? Even just data entry, chart audits, something like that that??

I know my aunt had a chart audit job that she got paid decently per chart. But we live in different states and her company only hired people who live there. She ended up having to get a different job because the census severely went down and she wasn't getting any work. But something like that would be great where there is no strict deadline. Work when I get a chance while kids are napping or whatever.
