$30 per hour for 1 child
Booked by 1 family in San Mateo, CA

My name is Isabella, I’m Brazilian, and I’m passionate about caring for both kids and pets. I’m responsible, patient, and creative, and I love creating a positive and fun environment for children. I have experience working with kids and currently help care for children at my church, which has strengthened my communication and nurturing skills. I also have experience with pet care and have a dog of my own, so I understand how important it is to keep pets loved, safe, and well cared for. I’m also preparing to start college to study psychology, as I genuinely enjoy understanding people and helping others. Families can count on me to be reliable, kind, and attentive to every detail that makes their home feel peaceful and cared for.

“Isabella arrived on time to our booking. We booked her services to allow the mom to have time to recover from the day. Isabella held baby with care and she was patient with baby when it was time to feed baby. She asked questions to be able to do the tasks correctly and was a calm presence in the house. Our family recommends her services.”

"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)."
