Hayat $30 per hour for 1 child

Hi, I’m Hayat! I’m a caring, patient, and dependable childcare professional with several years of experience supporting children from infancy through school age. I truly enjoy building strong, trusting relationships with both children and families, and creating a safe, nurturing space where kids feel happy, supported, and free to be themselves. I’ve had the joy of working in a variety of settings, including family homes, daycares, youth programs, and behavioral support roles. As a nanny, I cared for a child from 5 months to 3 years old while also supporting an older sibling before and after school and during school breaks. It was so rewarding to be part of their everyday routines and special milestones from first steps to new skills while providing gentle guidance, patience, and lots of encouragement. In daycare settings, I helped create fun and engaging activities for preschoolers, supported early learning, and balanced caring for multiple children while keeping routines structured and positive. My experience as a Behavioral Support Specialist allowed me to support children in building emotional regulation, social skills, and confidence, always using a calm, understanding approach. I’ve also worked as a Youth Advocate, where I planned after-school activities, helped with homework, and created meaningful experiences for children to feel supported and valued. Through my experience providing backup care through Care.com. Allowed me to quickly adapt to new routines, parenting styles, and household expectations while caring for infants and toddlers. This strengthened my flexibility, communication skills, and ability to confidently support children in new environments. I’m trained in CPR, First Aid, Safe Sleep, and more, and I always prioritize safety while keeping days fun, engaging, and full of learning. I also have a reliable car, which allows me to support transportation needs and outings. Families often describe me as warm, reliable, and attentive. I would love to become a positive, supportive presence in your child’s life and a trusted helping hand for 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."

"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)."
