Kay, child care - BS16 Mangotsfield

I am only 13 but am very mature for my age, I have 2 younger siblings and 2 cousins that I look after and enjoy babysitting when asked, I enjoy reading stories with little ones and am also clever for my age so could help children with their homework if needed by helping them work it out, but not giving them the answer. I can sing or do fun activities if need be but I do have school from 8:30 am till 4:00 pm. I am quite good at sport if that is needed and I'm looking for any ages to babysit under the age of 10. I'd prefer little girls but I am happy to babysit boys as well
