Nebyat $23 per hour for 1 child

Hi my name is nebyat , currently volunteering at Ashe prep center. As a parent of two children, I have developed strong skills in patience, communication, organization, and creating a safe and nurturing environment. I have also provided childcare for children of extended family members and close friends, giving me experience working with different ages, personalities, and individual needs. For the past two months, I have volunteered at Ashe Prep Early Learning Center, where I assist with daily activities and interact with young children in an early learning environment. This experience has strengthened my ability to support children’s social, emotional, and educational development while maintaining a structured and positive atmosphere. I am committed to providing reliable, attentive care and building trusting relationships with both children and their families. I take pride in creating an environment where children feel safe, respected, supported, and encouraged to learn and grow.

I am an experienced and professional nanny and bilingual kindergarten teacher. I have 15 years of experience as a nanny and 6 years of experience as a kindergarten teacher. I am a native Spanish speaker and I have conducted classrooms in both Spanish and English. I can work with children of any age from newborn to elementary. My greatest strengths are patience and the ability to construct a nurturing environment. I have a degree in early childhood education and I find great fulfillment in instructing young children. I believe in keeping the children active and will frequently take them to parks, playgrounds, libraries, museums, zoos, aquariums and any other educational activities. I will provide references upon request. Thanks, Maria

"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)."
