Hi my name is Cindy, I am 25!! I am Bilingual. I’ve lived in Marin county my entire life. I went to Novato high school so I’m very familiar with the area. I also graduated from The school of Paul Mitchell in Sacramento to get my cosmetology license. During high school I’ve volunteered at walker creek, elementary schools for walk-a-thons or after school activities, babysat for parents who had night time GED classes at Marin Oaks high school. I have 3 younger siblings and a older sister to. I have lots of experience with infants all the way to 16 yr olds! I’ve babysat for 6 years now and have many great references. I enjoy doing outdoor activities , watching movies, playing board games and arts & crafts! I’ve built great skills that will let me interact with your children in a great way ! & I will also make sure they grow and learn when I’m with them!! I also do dog boarding when on vacations and overnight sitting! I hope to hear from you soon!! I am also vaccinated and boosted 😊 Another thing to note is that I do have a 4 hour minimum for the day. If for any reason you do come home before the 4 hours or come home earlier from what time we agreed on I still expect to be paid the full amount. If you have any questions please feel free to message me.

“Incredible!!”

***Update: Please message me for availability- the calendar on here is rarely updated. Thank you! :-) ************************************************************** Hello! I'm a Bay Area native and I was a childcare provider and nanny for over 10 years in San Francisco before I began my teaching certification program. I really enjoy working with families and still keep in close contact with the last family I worked with. In the past, I've also worked for the Y.M.C.A. as a coach and teacher for children in their camp program. I love doing arts and crafts activities, and going on outside adventures with kids to parks, museums (California Academy of Sciences is a great one!), and libraries. Most of my past jobs working with families were referrals from other families I worked with, so this is my first time using an online site to apply for positions. My certifications are in Special Education EC-12th grade, E.S.L. EC-12th grade, English Language Arts and Reading 7th-12th grade, and General Education EC-6th grade. While working on my credential I completed internship hours in an elementary school classroom working with children on the Autism Spectrum. My experience in the internship was so inspiring that I decided to make Special Education a focus in teaching. I'm taking this semester off from teaching so I’m mostly tutoring, but also available for occasional babysitting. I really enjoy babysitting because it gives me the opportunity to be creative, no matter what age the child is, with play and learning activities. As an Educator, I am passionate about incorporating play into education to make learning accessible for every child. My schedule isn’t usually updated on the app, so please feel free to send me a message inquiring about a date. Thank you and I look forward to hearing from you! Sincerely, Reese

Howdy- My name is Kevin and I am excited to meet you and your family! I work full time at a highly regarded Montessori in Corte Madera, caring for 18-36 month-olds and also have experience in a classroom with ages 4-6. I hold an AMI assistant to infancy diploma from Montessori Northwest. If you’re struggling with toilet training, language, sleeping, behavioral issues ect, I have plenty of skills and strategies to share. In a non teacher role, I have lots of experience with all ages. I love being outside and playing sports. I can coach basketball, football, swimming, and skating on a meaningful level however, I’m happy to facilitate any kind of sport, craft, or activity. I am confident watching multiple children and pets at once. Ensuring everyone’s safety/comfort is always my main priority. I hope I get the opportunity to enrich your child’s experience on your night out!

Booked by 8 families in Mill Valley, CA

Hi there! My name is Leticia. I’m 26 years old and originally from Brazil. I’ve been working as a nanny for 7 years and have experience with children of all ages, from infants to teenagers. I’m CPR/First Aid certified and known for being caring, responsible, patient, and creative. Throughout the years, I’ve worked in different settings, including nanny share with infants and caring for +3 children at once, which made me comfortable managing routines, multitasking, and adapting to each child’s needs. I enjoy exploring outdoors with kids, and when we’re inside, getting creative with arts and crafts and engaging activities. I’m available for occasional babysitting and date nights, primarily in Marin County, but I’m also open to San Francisco. I have my own car, a clean driving record, and I speak fluent English and Portuguese. Strong references are available upon request. I’d love to help out! 🌻💕
