Experienced NICU nurse of 6 years and postpartum doula, DONA trained, providing expert newborn care and in-home support for families. Skilled in helping with feeding, general newborn care and calming techniques, including working with multiples. I offer a blend of professional care and light household help to create a calm, supported environment for both baby and parents. I also assist with older children as well, but my speciality is newborn care.
Hi! My name is Beatriz, but most people call me Bea. I’m a caring, patient, and dependable childcare provider and a mom to a wonderful six year old boy. My love for working with children began at 14 when I helped care for children ages 0–5 at my church. Since then, I’ve gained experience in childcare and school settings including working as a paraprofessional. I also have experience supporting children with special needs and understand the importance of patience, flexibility, and getting to know each child’s individual needs. I have completed 16 units in early childhood education, which have helped me better understand children’s development and how to support their learning through play and everyday routines. I enjoy creating a safe, nurturing environment where children feel comfortable being themselves, exploring, and growing. As a parent, I know how much trust it takes to leave your child in someone else’s care. I value open communication with families and bring kindness, attentiveness, and a strong sense of responsibility to my work. I am bilingual in English and Spanish. I’d love the opportunity to get to know your family and support your little one!
“Bea was on time and gave thorough feedback om how everything went. She was kind and my little guy had a good time with her. 😊🧡”
For two decades, I've dedicated myself to nurturing young minds and creating enriching environments for children. My passion stems from witnessing their incredible growth and development. I enjoy using my creative and imaginative personality to engage children in outdoor sports, board games, and educational activities. I'm very comfortable enforcing household rules and caring up to two children, ages newborn to to seven. I maintain open communication with parents, providing updated through verbal discussions or text, always respecting your preferred method. My background includes Early Childhood Education coursework, First Aid training, and CPR Training. I'm also happy to help with cooking and crafts. I hope to bring my experience and love for childcare to your family.
I’am a calm, attentive, and responsible babysitter who genuinely enjoys spending time with children. I focus on creating a safe, positive environment where kids feel comfortable, heard, and engaged. I’m patient and adaptable, whether that means helping with homework, organizing fun and creative activities, or simply sticking to a child’s routine so they feel secure. I pay close attention to details—like dietary needs, bedtime schedules, and house rules—and I take those seriously. I also believe communication is key, so I make sure to keep parents informed and follow their preferences closely. At the same time, I bring a warm, friendly energy so kids see me as someone they can trust and have fun with, not just someone in charge. Overall, I aim to be dependable, nurturing, and someone both parents and children feel confident with.

“Mayra was our daughter's nanny for 1 year (6-18 months of age) and we had a wonderful experience. We met Mayra during the thick of the pandemic and we could not have had a better partner. Our daughter, my wife and i love Mayra and it was with a very heavy heart that we parted ways when we determined that our daughter needed to go to daycare/school. Mayra was always extremely careful and loving with our daughter and we always felt she was in great hands. She formed a very especial bond with our daughter and always stimulated her physically and intellectually. Our daughter easily completed all of the age-appropriate transitions with Mayra's help. They read, played, went to the park, and did arts and crafts. Mayra also cooked frequently for our daughter and fed her healthy and balanced meals. Our daughter was always happy to see Mayra. She has a wonderfully calm demeanor that helped our daughter be calm most of the times. When our daughter slept Mayra helped us with our baby's laundry and folding clothes. We have met other nannies and Mayra definitely stands out. From a personality perspective, Mayra is very discreet, easy going and a pleasure to be around. We highly recommend her.”
