Jobs i can do with young son in tow?

My son is currently at childminders so i can work for myself part time. the tax credits childcare element was supposed to pay towards his childcare but have now told me they no longer can. it seems silly to continue with sending him to the minder as the work i do whilst he is there is barely more than what i pay the childminder (there is literally pounds in it) so it just cancels it straight out. i think i have decided to remove him from the minders as one of my morning jobs (looking after horses at a stable yard) he comes with me if needs be and sits in the car playing as i am only 30mins or so (is well paid job but not regular and not consistent). ideally i would like a job where i can take him with me, or that provides a creche or something- he is 15months- someone have any ideas. furthermore someone know of any genuine work from home jobs that dont involve an investment? thanks

If you own your car, you could deliver catalogues for the likes of next and also do there deliveries, you can take your kid out in the car with you.
