Valquiria $30 per hour for 1 child

Hi! My name is Valquiria, and I’m an experienced, reliable caregiver with a strong background in childcare and mental health. I worked as an au pair for two girls in Chicago, helping with driving, homework, meals, and daily routines. I’ve also cared for three children (ages 9, 12, and 14) and have experience supporting a neurodivergent child (7) and two girls (5 and 9), adapting to each child’s unique needs. I’m a mental health counselor building my private practice and looking to work a few hours a week. I’m calm, patient, organized, and emotionally attuned to children. I can drive and am comfortable with school pick-ups, activities, and errands. I look forward to supporting your family with safe, thoughtful, and dependable care.

Nobuhle

$30 per hour for 1 child
Booked by 1 family in Mercer Island, WA

Hi! I'm Nobuhle, 27. I am looking for a FULL TIME (preferably) position beginning September 28th when I will be available for my current part time job. I have been doing childcare for last 6 years, and in the last 2 I have only worked with multiples coincidentally. I was doing a live in position for one year 6 months and have found a passion for childcare. I grew up with a single mother and I know if she could afford childcare I would’ve had a much easier childhood, I believe that it takes a village to raise a child & I want to be apart of your village! I'm a caring, reliable, and energetic nanny who absolutely loves working with kids! My favourite part about childcare is watching the children grow, reach milestones and learning their unique personalities. I'm that sitter who will get on the floor and play, help with homework, handle bedtime without a fuss, and leave the house tidier than I found it. Parents say I'm super patient, responsible, soft spoke and easy to communicate with. Your little ones' safety and happiness are always my #1 priority. I am CPR & first aid trained! With other advanced childcare qualifications! I love creative play, reading stories, outdoor adventures, and making healthy snacks. Happy to help with light meal prep, homework, and bedtime routines. I have had great experiences with families in the past and can provide references and a detailed resume on request. I am open and available for in person and virtual interviews too! I'd love to meet 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)."
