Do you have a second job and how well could you manage two or more jobs?

I used to work 2 part time jobs and i managed it pretty well. sometimes it got a little overwhelming ontop of being a mom with a toddler and stuff but i managed. with my last 2 kids i havent worked but id eventually like to go back to work.

I am currently very busy as I have a job as a deputy in a children's day nursery, for 3 days sometimes 4 a week. Recently I got a job training to assess NVQ's in childcare and am training up here too, which at the moment is for about 4 hours a week, but from September will go up. Once trained, hopefully by September my hours will increase again. I also babysit for a professional company, receiving on average 2-3 jobs a month, I ebay, I sell children's clothes and I go to college on Tuesdays (up until December anyway).
I love it, and it keeps me busy, but I still manage to find the time to spend time at home with my teenage son, and try to keep the house running. Apparently though I am a good role model according to my son, and in comparison to his Dad that doesn't work and hasnt for years, he knows who he wants to take after which is good.
Financially I have yet to benefit, as the ebaying is going slowly, the childrens clothes selling will pick up nearer christmas and the assessing I have yet to get paid for, but in the end it will be worth it. Can't wait to treat my son who has had to go without for a long time, and finally treat myself!
