My passion and calling is caring for children. The safety and well being of my charges are paramount to me. I have 30 + years of experience working with children (including but not limited to children with various special needs) in Brazil, Germany, India, Hawaii and now here in CA. Tending to each child's needs with regard to his/her unique personality and developmental stages is my main goal, while still having fun in the process! Families that have experienced my care services describe me as reliable, creative, accommodating, patient, knowledgeable, enthusiastic, loving, and firm when needed (see reviews). Our time together is filled with adventures, age-appropriate activities, reading, imaginative play, walks in nature, music, Yoga, dance, and lots of love. My background is in Speech and Language Therapy, Montessori, and Infant/ Child Development. I am a mother of a 27 year-old son (graduated from UC Berkeley /Computer Science) and a 24 year-old daughter. (UC Santa Cruz /CS). Current CPR/First Aid. Trust Line registered, clean driving record and I own a reliable car. I do not smoke, use drugs, or drink alcohol. During the time your child is under my care, my phone usage is limited to communicate with you. I am fully present, engaging and giving the children my undivided attention. Rates vary, depending on distance and job description. Looking forward to hearing from you. Thank you!
“Nadia was amazing with our son. She was warm, punctual, thorough, and communicative. Our son loved her!”
Response will be in 1 hour thanks I am available on a limited basis please send me a DM, thank you! Extensive experience as a nanny Educator / Scholar ( currently attending) Parent (2 college kids) Currently holding all five star reviews from past and present clients through this platform. As a nanny I’m passionate about helping parents build up great kids. I’m currently taking online classes and will continue toward completion of my degree in Early Childhood Development and Psychology. I homeschooled both of my children until 1st grade ( both are college) Homeschooling is about planning, strategy and creativity. I consider myself a career nanny. I have 10+ years, of professional experience. In the last four years, I have regained experience in newborn , infants and toddlers ( this includes working with siblings and of nanny share as well ) my calm, nurturing manner is reassuring to babies , children and parents alike. I feel that to be a a great nanny , you must have it in your heart . The character traits of patience, kindness, boundaries, empathy, compassion, calmness, acceptance, positive reinforcement, creativity, playfulness are all part of who I am. I am specialized in the areas of sleep training, routine establishment, developmental play and excellent soothing techniques. I also am very skilled in making baby food from scratch for high nutrition and health. I accept per diem work with toddlers / school age children and focus on teaching them breath work to calm themselves ( if an emotional outburst occurs) It is very common as they have many feelings and don’t always know what words to use to express it , this includes self regulation and choices including Baby Signing which encourages them to communicate well and become verbal communicators earlier. I have many other specialized skills to offer. In my free time I enjoy spending time with my family, cooking reading, dancing ( with my husband) sports like tennis, swimming, pickle ball, fast walking, and yoga for fitness. I believe that the secret to a happy life comes from having a deeply grateful heart.
Hello Urbansitter parents! I’ve been babysitting children, pet sitting & house sitting for 35+ years, but the last 9yrs here on Urbansitter. I just retired early from my full time job at Kaiser Permanente where I worked for the past 25 years. Prior to that, I worked as a medical assistant for a private Pediatrics office in San Mateo for 5 years. I love kids of any age, enjoy playing games, reading, going to the park, arts & crafts, cooking/baking, doing puzzles or watching a movie with them. I have many years experience with newborns/infants, toddlers, grade school kids & watching multiple kids together. I also drive some of the neighborhood kids where I live, to and from school and their afterschool activities. I have car seats available for toddlers & grade school kids. I have 1 rescue pup, love the outdoors & I have a passion for rescue animals, so I am more than willing to help out with your pets, big or small! Please feel free to contact me with any questions you might have. I try to keep my calendar as updated as possible, but you can always message me to check on the availability you need. I am COVID vaccinated & can supply proof of vaccinations. I am also First Aid, CPR & AED certified as well as fingerprinted & background checked. I look forward to meeting you & your family!
Hello! My name is Kassandra, however, I prefer to go by Kassie. (I apologize that video in my profile is old, I will update it when I can). I am a student who works as a waitress as it is accommodating. I am currently enrolled at SJSU as a Psychology major with a double minor in Child Development and Sociology. I’m looking down a career pathway of becoming a Child Psychologist, therapist/counselor, school counselor, behaviorist therapist or something along that path. I love working with children and I want to make a career out of it. I have received AAs in Psychology, Allied Health, Natural Science and Health Education. I love to help others. I’ve always wanted to follow in my grandma’s footsteps with saving lives and making a difference by working in the medical field. I am COVID-19 vaccinated and boosted as well as flu vaccinated. I have also received all my other vaccines. My experience with children goes back to when I first started babysitting at the age of 12. I have worked at day cares where I have experience with children from infancy to 15 years of age. I am comfortable with all age groups. I do not smoke. I love animals as well so pets are never an issue! I have experience house sitting/petsitting as well. I have been house sitting/petsitting since I was 13 years old. It first started out with watching my neighbor’s house and cats while they were gone and progressed to dog sitting/cat sitting at other people’s houses. I am very responsible and respectful of other people's homes. I clean up after myself and make sure the house looks like it did when I arrived.
“So friendly, on time and professional ”

"UrbanSitter is my go-to for quality sitters! I can book weeks ahead of time or easily find a same-day sitter when in a bind. I even hired a part-time nanny during a daycare transition. Customer service is helpful and babysitters respond in a timely manner."
