Hi! My name is Gina, and I’m from Colombia. I’m looking for extra babysitting opportunities. I’m a responsible, respectful, and loving person who truly enjoys helping families and caring for children. Currently, I take care of twin 2-year-olds and their siblings of 4 and 7 years old. I have experience caring for children of different ages — from infants to school-aged kids. In Colombia, I worked with two children, aged 8 and 1, which gave me valuable experience with different developmental stages. I enjoy doing activities such as arts and crafts, reading, outdoor play, and helping with routines. My daily tasks include cooking for the kids, school pick-up, laundry, organizing play areas, and assisting with nap and bedtime routines. I offer child care, and pet care. I also love animals! I have pets myself and I’m very comfortable around dogs and cats. I can help with walking, feeding, and playing with your pets if needed.

“Yinna was prompt and patient with our almost 3 year old. ”

Hi I’m Layci and I have been an educator for over 10 years and working as an elementary school teacher for the past 8 years teaching 1st-6th grades. I have been a nanny and babysitter for families all around the Bay Area for over 14 years. I have experience with newborns, infants, toddlers and children with special needs. I have helped families as a night nanny and with various medical needs as well. I love animals and have grown up around cats, dogs, geckos, hamsters and bunnies. I also have my own urban outdoor garden and love indoor plants as well. I am reliable, confident, and fun. I am firm but warm and while I set boundaries, I also adhere and defer to family expectations and dynamics. I love working with kids and enjoy being able to create engaging and fun activities. I will engage in imaginative play, arts and crafts, and science experiments. I can cook and help with light clean up. I have references upon request, and happy to provide a cell number if you are interested in talking more. I can’t wait to get to know your family!

“Layci was great! She came well prepared with activities and my daughter had so much fun with her.”

Hi, my name is Shirley and I’m a 39yr old female. I’m offering child care, after school/activities, crafts, household services, and walks to the park would be great. I’m an event planner. I’ve been in the bay for about 20yrs and currently living in San Francisco. I love kids and animals. I enjoy working out, traveling, taking care of my indoor plants, and spend time with family and friends on my free time. I’m pretty responsive to keeping you updated with your kids. I like to keep things clean and organized. Depending on my schedule, I’m free on weekends and certain holidays. Currently part-time with another family. Feel free to reach out if you have questions.
