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!

"We absolutely LOVE Isa — our family was so fortunate to have found her through UrbanSitter. I'm a first-time mom, and it took me a long time to find a full-time nanny I could trust to care for our sweet infant boy. Our boy connected with her immediately, and we couldn't have asked for anyone else to care for him. Her calming presence was also perfect for parents like us who work from home. We feel so lucky UrbanSitter helped us find someone who has truly become a part of our family."

"I was so stressed about finding a part-time nanny for my 14-month-old son, who has moderate separation anxiety and hadn't been left with anyone but family before, but we were both immediately at ease in Buhay's presence. Her empathy and commitment to understanding child development are apparent in every interaction I've witnessed between her and my toddler. I feel very lucky to have found her."

Kamilah W., mom of one

photo of quoted parent Eric

"Erna watched our now 5 year old daughter and 3 year old son for a few years. She is punctual, responsible, honest, and playful. What we appreciated most was that she was thoughtful in ensuring that we had a little break; for example, when the kids were clingy, she was able to divert their attention with games or songs or walks to the park. We felt very comfortable leaving our kids with Erna because of her caring nature and experience that spans a decade (including being a live-in nanny)."
