Jobs with a baby?

I'm just wondering what jobs you could do that you could either do from home or take your baby with you (he's 9 months) I run dance classes for children but it's only 4 hours a week and that's the only time my mum can look after baby and I think it would work out too expensive to put him in childcare. I worked out the cheapest place is £5 and minimum wage is like £8 or a bit less I'm not sure. so I'd earn less an hour than I would to pay childcare. so figured a job where I can take him with me or do from home would be best. any ideas?
