Atefeh $20 per hour for 1 child

As a mother of two,with 19 years of childcare experience,, I understand the importance of finding the right caregiver for your children. My experience comes from owning my own in-home daycare till 6 yrs ago.Then I transitioned into customer service work..While I have enjoyed my time in customer service, I have come to realize how much I miss caring for children and infants. Babysitting/nannying is the perfect opportunity for me to fill that void and put a Smile on my face.I am a patient, caring and loving person who is easy to get along with.I strongly believe in great communication and will always keep you informed about your child's well-being. Aside from loving and caring for children, I am also passionate about cleaning, chores and organizing. I love being a helping hand to anything that needs to be done at your house. Additionally, I am an animal lover and will happily care for your pets as well. I understand that finding the right caregiver can be a daunting task. That's why I am happy to provide references upon request. I look forward to the opportunity to meet your family and your precious children. Thank you for taking the time to read my bio.

"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)."
