Emily, sitter in Southend-on-sea

My name is emily and I am 17 years old. I am currently studying A levels- pyschology, english, rs and media. I understand that I am young however I do have plenty of experience as I have looked after and cared for my younger siblings who are 1 and 3 so I have the knowledge of what they need and how to behave around them. Not only this but I have also looked after my cousins who are 6 and 8, meaning I have experience of older children too. I am hardworking, fun, friendly and trustworthy. I understand the difficulty of finding someone to care for your children as it requires some serious thought but I can assure you that I would not let you down. I would cook, clean, play... Any task you would like me to do I would be happy to do it. I've witnessed first hand how hard it can be to go out to work or for fun when having children so I would like to be here for you whenever possible to make your life easier.
I am looking for a babysitting job. Something that is occasionall however I am happy for it to be a regular thing.
