I am writing this letter to kindly provide my interest in working as a child-care responsible, due to your advertisement in the local magazine. It would be efficient if knew, that I was working as a baby seater for three years with a Spanish family in Sydney which had a couple of toddlers until they had to leave Australia for another country whereas, I still have a nice relationship with them I had to look for a new job and in these three years of my professional career life I have promoted my language skills to three languages beside Persian which is my native language, I have the national certificate of kids caring which I have attached to the letter.
