Hello! My name is Jenna and I recently graduated from CSU East Bay. I am offering childcare and pet care services. Over the years I have babysat numerous times for neighbors or family friends from children ages 1-10. Previously I worked at a petting zoo and managed groups of children from ages 3-14. I can also help with homework, especially in the science area as I have a bachelors in biology. In my free time I enjoy reading, drawing, painting, and crocheting. I have around 7 years of experience working with various types of farm animals and I am comfortable taking care of any animal! Upon request I’d be happy to give references.
“Such a sweet kind young woman ”
My name is Fernanda, and I am from Colombia. I am university trained and licensed as a teacher in Colombia where I taught children ages 4 years to 14 years old. I am fluent in English and Spanish and for the past 2 years have been employed as a nanny caring for children ages 6 months to 3 years old. I am a very patient, responsible, and dependable person who is about promoting the well-being and overall development of children.
“Maria (she goes by Fernanda) was great with my two year old. She got here right as I was in the middle of my daughter having just had an accident. Fernanda took over and handled it without complaint and helped change her. My toddler warmed up to her immediately and Fernanda took great care of her. Would definitely have her back!”
I have professional experience caring for babies and young children, with 5+ years of childcare experience, including nannying and family support. I’m comfortable with daily routines, meals, play, naps, school drop-offs and pickups, and creating a safe, warm, and engaging environment for children. I also have experience helping families with light housekeeping and home organization, as well as pet care. I’m reliable, caring, organized, and attentive to the needs of both children and the household. Thank you, Bruna
“Very detail oriented and caring. Will definitely work together again.”
Hi my name is Breanna, I am looking for a nanny share position. I currently have a almost 2 year old and am looking to bring her along with me. She’s very easy going and independent and loves going on walks along with other activities! I have been working with children for several years; caring for a newborn and triplets were two of my first babysitting jobs. Along with having worked with kids of all ages and having three younger siblings, I am CPR and first aid certified. I love children and love being a mother and am excited to find the right family for us!
Hi everyone, my name is Shelby. I'm currently a 5th-8th grade educator but have taken care of newborns, and worked professionally in environments with children as young as 3 and up to 17. I love creating fun and inclusive spaces for children which is why I've dedicated the last 8 years to working with them! I'm also a huge pet lover (with a rabbit and pug of my own) and would love to meet any fur babies of yours 😄. Feel free to reach out if you have any questions about my qualifications or experiences. I'm CPR/First Aid/AED certified.
