Second, congrats on the kid(s). They're way more fulfilling and rewarding than any paid jobs. If I could I'd quit now and be a SAHD.
I've met other parents at our local park with a similar dilemma. Many of the mothers had (prior to kids) better jobs than mine and are very driven and business savvy. They have signed up for various work-from-home/sell-from-home web franchises that sell all sorts of products and services - kids clothes, books, hair accessories, product reviewers, mommy-blogs (want to do a tech version of thepioneerwoman.com? ) etc.
Do you have a neighbor hood association? or local mothers/parents/schoolparents group? We recently got signed up to nextdoor.com and a lot of neighbors have listed their occupations/jobs/skills/workplaces. Almost every business needs someone to update their website with fresh content, articles, SEO changes, proof reading, link checking, promotions, groupon landing pages, facebook pages, tweet writing, social media etc. Or sales support work like searching for potential prospects to give to their sales people. It can be done anytime so you can work at night when the kid(s) are asleep. Either volunteer for (or try starting up) your neighborhood/association web site or get to know local people, then start asking around for anyone that needs help with their website. It's a lot less risky than finding leads on websites like elance, craigslist etc and you're more likely to be paid if you are local.
We have former employees that are SAHMs still working on an hourly basis on some tasks. They're reliable and can do work for which we can't justify a full time job.
