Sophie, baby sitter in Westerleigh BS37

I am a 17 year old girl who is currently in sixth form studying forensic science and health and social care at level 3. I have also done level 2 health and social care. I don't know whether this job is available for someone of my age but I am hoping I will be given the chance to? I am available in the week from 3 o'clock (sometimes earlier) I can do weekends as well. I have a younger sister who is 4 and a younger brother who is nearly 2 so I have experience with looking after children. Since my sister was a couple months old I have babysat her and have done ever since so I know how to care for children from a young age. I am currently working as a waitress but I want some experience with caring for children as I am interested in doing this when in later life. I don't mind babysitting a child that is a couple month old or a teenager. I would like really appreciate it if I was given this opportunity.
Thank you.
