Apart from raising two children of my own, I have worked for the last 13 years with children aged 7 - 11 in my local junior school. Although I work with many children during the school day, my main job is working 1:1 in class supporting children with special needs.
I am also a registered sitter with another local babysitting agency, having worked for them for approximately 2 years.
I also am a regular babysitter for friends and colleagues on an ad-hoc basis. 
In addition I have worked with children of various ages in different groups at my local church over the past 22 years.
