Hi! I’m Vera. I’m currently studying for my bachelor’s degree in Accounting and have been caring for children of all ages, from newborns to school-aged kids. I’ve cared for infants, toddlers, and older children through children’s camps, helping family members and day care. I’m CPR and First Aid certified, so safety is always my top priority. I love creating fun, engaging activities that keep kids learning whether we’re painting, baking, riding bikes or scooters, visiting the skate park, practicing piano, guitar, or working through homework together. Along with childcare, I also offer household assistance, including meal prep, cooking, laundry, organizing, light housekeeping, errands, and transportation to and from school or activities. I’m comfortable with pets too.

Hi there! I am an experienced nanny and sitter as well as a former preschool and daycare teacher. I have STARS training, two bachelor degrees, reliable transportation and a clean background. I have been working with children for the last 20 years and really enjoy it! Children have always been my passion, and I haven't found anything more rewarding than teaching and taking care of children. For fun I enjoy movies, music, arts and crafts, writing, photography, road trips and spending time with my dog.

"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."

"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)."
