Sharna Jade, sitter in Arnold

My name is Sharna and I'm currently 23 years old, At the moment I'm in full time education studying for a social science diploma at King Edwards VI College I'm in my second year, however it's only one day a week 1:30pm till 7:30pm on Wednesdays so I do have a lot of free time. I plan to take my diploma and top it up to a degree at Middlesex university for the third year. My hope in the future is to become a clinical psychologist.
I do school runs for a lady who has now become a family friend since 03/2013 and I recently began cleaning their home for them on Fridays. The ages of these children are 7 and 6. The youngest is in a specialist school as he has mild learning difficulties and is such a joy to take care of.
I have lived with my sister since our parents sadly passed at the age of 13, at the time my sister had two children aged 6 and 6 months. Now she has another child who is 2 and a 4 month old baby girl (12 year old boy, 7 year old girl, 2 year old girl and a 4 month old girl) so I'd say I'm very good with children as I've had a lot of hands on experience and practice.
I'm a good listener, caring and described as wise for my age. I don't drink and I don't smoke at all, personally I'm not religious however I have a lot of respect for those who do have a faith. I can cook, read to children, sing with them and have fun making them laugh and smile.
I know families have particular routines and 'their ways' of doing things, I'm happy to learn and adapt.
