Milli, sitter in London WC2R

I live in Tooting, London. I come from a big family and often babysit my younger siblings (5 and 8 year old) and younger cousins ranging from 1 year to 10 year olds and also babysit for family friends. I'm 18 and have just finished sixth form so I am looking for a summer job whilst gaining experience in childcare as I'm planning to go to college to train to become a full time nanny. I'm able to help with homework up to secondary school level and happy to cook and help with housework if needed.
