I'm looking for a reliable after-school babysitter for my two kids aged 6 and 9. The role would involve collecting them from school at 3:15 PM, supervising homework, preparing a light snack, and ensuring they get to after-school activities twice a week. We prefer someone with previous childcare experience, basic first aid knowledge, and good communication. Ideally, the schedule would be Mon, Wed, Fri 3:15 PM to 6:00 PM, with occasional longer hours on days when I have meetings. We live near central London and can provide a secure, smoke-free home environment. A quick care plan and a couple of references would be appreciated.
