I have been working with children since I was in high school (summer camps, volunteering, teaching module) and have experience in London for the past 3 years now.  
I have started looking after children aged 7-11 and then had sole charge of a 2 years old girl, a 1 years old girl and I am looking after 2 children at the moment, aged 4 (girl) and 5 (boy). 
I am very confident with children and very spontaneous when it comes to activities.
