Hello! My name is Leticia, and I’m from Brazil. I hold a degree in Early Childhood Education from the Federal University of Sergipe, a well-respected state university in Brazil. I absolutely love caring for babies and children and have many years of experience working as a nanny. I’m excited to learn more about your family and how I can support you! I speak Portuguese and some English, and I’m confident we can communicate well. References are available upon request. Thank you so much!!😊

“Leticia has worked for me as a house sitter and also as a chef. She's very talented in the kitchen and extremely reliable. Most recently, Leticia has helped me manage my household while my husband and I were away. She made sure the house was secure and that other staff (gardeners, etc.) were able to perform their duties with no obstacles. I highly recommend Leticia to help your family!”

"When we hired Amani, we felt like we hit the jackpot. We were very lucky to find her on UrbanSitter at the beginning of school year. She was picking up kids from school, taking them to afternoon activities, helping them with assignments. She prepped food for them, helped organize their closets and keep their spaces neat and orderly. We would hire her again in a heartbeat."
