Health & Safety Note: Because I often care for 2–3 different families in a single day, I do my best to keep everyone healthy and safe. For this reason, I’m not able to provide care for sick children or in homes where someone is currently unwell (cold, flu, fever, cough, etc.). If I arrive and notice signs of illness that I wasn’t informed about in advance, I may need to step away from the booking to avoid the risk of spreading anything to other children and families. Thank you so much for your understanding and support in keeping everyone well! ❤️ I’m a caring and experienced nanny with over 15 years of working with children of all ages — from tiny newborns to busy school-aged kids. I’ve worn many hats over the years: babysitter, summer camp group leader, and even some families trusted to help interview and choose the right nanny. I truly love what I do and always aim to create a warm, safe, and loving space where children can feel secure and thrive. Supporting parents and becoming a trusted part of the family is the heart of my work.
