Deena $25 per hour for 1 child
Hi! My name is Deena and I'm a first-year college student at UC Urvine with a genuine love for working with children. I've been helping out with my younger brother since I was 7, which taught me patience, responsibility, and how to connect with kids of all ages. I enjoy creating a safe, fun, and supportive environment where children feel comfortable and cared for. I plan to become a child therapist in the future, so working with kids is something I'm truly passionate about. Families can count on me to be attentive, nurturing, and dependable.

My name is Markie and I am a 29 year-old with a B.A. in Legal Studies and Politics. I have just completed law school and I am currently awaiting CA Bar results. I am the middle child of 5 children and have always played a huge role in looking after my siblings. I have worked as an au pair or live-in nanny and tutor in Italy for two young children. I absolutely love children and even took several child development classes in my undergraduate career. I am also CPR certified. I have also been told I can make some amazing Mexican food dishes!
“Markie! Is absolutely amazing. We will definitely be reaching out to her again. She was great with my kiddo and super friendly!”

Booked by 1 family in Costa Mesa, CA
I’m currently a college student at USC with 4 years of tutoring experience, working with students of all ages to help them grow academically and build confidence. For the past 3 years, I’ve also babysat part-time for multiple families, primarily caring for children ages 1 and up. I’ve handled infants on several occasions and would love to gain more hands-on experience with younger babies as well. I’m calm under pressure, very organized, and always prioritize creating a safe, engaging, and nurturing environment for kids. Whether it’s helping with homework, preparing snacks, playing games, or managing bedtime routines, I’m happy to support families however I can. As a student, I bring energy and strong communication skills. I truly enjoy building meaningful connections with both kids and parents, and I’m committed to making your family’s day a little easier.
