Hi families! I'm Maria Laura, I'm 30 years old and I'm from Brazil. The first thing that you need to know about me is that I will always give my best for your kids. I will always provide the best care possible and make sure they are safe and happy. I studied psychology and I'm very interested in child development. I'm working with children for more than 10 years: in schools, kindergarten, nanny including with special needs. I loved all my works and I'm really grateful! I have kept in me a lot of love for the kids that have gone through my life. If you want and if you allow me, I will be really happy teaching Portuguese to your children's. Also, I'm really patient and proactive! I love to discover activities to do with them but I also like to hear about them and what they like or would like to do. I was raised with the Montessori philosophy and I studied it for a while as well. I am also full vaccinated + booster If you have any question, is gonna be a pleasure to answer! Thank you so much.

Hi there! I'm Emily. I just moved back to the PNW after 7 years in NYC. I joined UrbanSitter because I love kids and want to spend time teaching, playing, and learning with children. I love arts & crafts and the outdoors. I'm always up for anything! I have experience with children of all ages (newborn to teen) and was a counselor for a summer sleepaway camp for 5 consecutive years. Additionally, I am Red Cross and CPR certified.

"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)."
