Hi! I’m Eva, a lifelong childcare enthusiast with just shy of 20 years of experience supporting families and nurturing kids of all ages, from newborns to tweens. I have extensive newborn/infant experience and am well versed in all things diapers, bottles, swaddles, and infant sleep! I often support twins and triplets, and families with 3+ young children. I’ve been a pediatric play based therapy provider for 13 years and I work full-time as a behavior analyst with children ages one to six, helping them build independence through silliness, play, routine, and connection! Whether it's navigating toddler play or supporting school-age routines, I aim to bring a calm, joyful, and dependable presence to every family I work with. Here’s a quick snapshot of my nanny experience in addition to hundreds of evening and weekend babysitting jobs for many families: Triplet Caregiver (Part-Time (20 hrs a week) from 3 months to 3 years): Provided care M-F, from 9 AM to 1 PM including meals, naps, play, outings, and household help. Continued to support the family for years through evening and weekend care after the kids began pre-school. Full-Time Nanny (40 hrs/week): Supported two sisters (ages 1.5 and 3) with daily routines, drop-off/pickup, meals, outings, playtime and household tasks becoming an extension of their family. Current Weekly Care: Evening/weekend sitter for two sweet brothers (ages 2 and 4), managing everything from active play to community adventures to bedtime routines. My approach is warm, patient, and play-based and I will aim to adapt to your family’s values and routines while creating a safe, engaging, and supportive environment for your child (Whether we’re exploring the outdoors, making up silly stories, or winding down for bedtime).

Hi- my name is Adriana. I am a biology graduate at SFSU and I am pursuing a career in Nursing. I have been nannying/sitting for over 8 years now and I have loved it ever since! I have cared for children from infant to teenage years and have gained tons of experience not only from working with children around my neighborhood but also from caring for my cousins and now nephews and niece! I love being able to play and be a kid again and learning new things from children as well. I love walks to the park, playing hide and go seek and even tag! I also like visits to the library and museum. I do ask for a 3 hr minimum payment for cancellations that are less than 24hrs, thank you!

I am a caring, responsible, and reliable caregiver with experience working with infants and toddlers. I truly enjoy creating a safe, nurturing, and engaging environment where children feel loved, supported, and encouraged to learn and grow. I have experience with daily childcare routines, including feeding, diaper changes, meal preparation, nap schedules, playtime, and age-appropriate developmental activities. I love planning fun and educational activities such as reading, arts and crafts, sensory play, music, outdoor adventures, and creative games that encourage learning through play. Families describe me as patient, attentive, trustworthy, organized, and proactive. I believe open communication is essential, and I always strive to support each family's routines, values, and parenting style. My most recent position was caring for a baby for over a year, from 9 months old to 21 months old. I have also cared for newborns, 3-month-old infants, and 1-year-olds, which has given me a strong understanding of the different stages of infant development and the unique needs of each age. In addition, I have experience caring for children ages 4, 7, and 9, as well as managing the needs of multiple children at once. I look forward to meeting your family!

“Jani has a warm, grounded energy, and she was incredible with our 8-month-old! She’s super experienced with infants: she jumped right in, naps and bottles went smoothly, and she was a great communicator. She was happy to adapt to our routine. We will definitely book her again!”
