I'm looking for a part time teaching job 3 days per week and as a single parent I know tax credits will pay some of my childcare costs. I'm wondering about an au pair. I have 3dc aged 9, 4 and almost 3. The youngest will be in preschool so I will need them all to be dropped off in the morning and then picked up at 11.30am and 3pm 3 days a week. I should be home by 4.30. I could really do with evening babysitting and some help with housework which is why an aupair sounds like a good solution. Is this feasible with tax credits?
