My questions are kinda complicated, I only work 1 day a week and I don't know if it's worth my while increasing hours and putting Brody into nursery to make me entitled to SMP from work (I'm not entitled to at the moment) or to just carry on like this and get about £40 a week maternity allowance. If I increase my hours my tax credits will go down obviously, how do you work out the best way to do it??
