I have a 4 year old who started reception in September. I'm a single parent and I work 30 hours per week, usually 9am-3.30pm (half an hour for lunch unpaid). I work from home 2 days per week. On my WFH days I'm thinking of using my lunch to pick DD up from school at 1.50pm, then bring her home and log back on for the remaining 1.5 hours of my working day and she can do her homework or watch TV. She's older now so should be fine to occupy herself and it will save me £70 per day not having to pay childcare to pick her up and look after her for 90 minutes. AIBU?
