Here's a sample cover letter for a host family as an au pair in Ireland. You can customize it with more details about your experience and personality.
My name is Gema, I'm from Burgos, Spain, and I'm very excited about the opportunity to be your au pair. I consider myself an active, outgoing, and curious person, with a great passion for caring for children, animals, and nature.

I have experience in childcare, having worked as a nanny for children ages 2 to 10 and also cared for relatives. I love spending time with children, playing with them, helping them with their activities, and encouraging their learning in a fun and educational way. Additionally, I have experience in customer service and reception, which has allowed me to develop communication, patience, and organizational skills.

I would like to be an au pair in Ireland because I want to improve my English and immerse myself in the country's culture. I believe living with a local family will be an enriching experience for both me and you. I'm delighted to be able to help with childcare and some household chores while I learn more about your lifestyle.

I'm a responsible, flexible, and caring person. I enjoy outdoor activities, hiking, running, and sports, so I'm happy to play with the children and share active moments with them. I've also held a driver's license since I was 18, which allows me to help with transportation if necessary.

I'm very excited about becoming part of your family and creating unforgettable memories together. I hope to have the opportunity to meet you soon and answer any questions you may have.

Thank you very much for your time and consideration.

Sincerely,
Gema
