Caitlin, after-school childcare in Londonderry

I’m Caitlin, and I’m 15 years old, I’m looking for a job for a little extra money to look after children, as I would love to work with children in the future, I would love a job for the rest of the summer and weekends when school starts up again. I don’t have much experience but I sometimes look after my 5 year old sister. I could do chores around the house and wouldn’t mind helpin with any homework, I would prefer to work with children in primary school or before!
