Adi $22 per hour for 1 child

Hello families! My name is Adi, although most of my clients know me as LEIGH, and I’m excited to introduce myself to you. I am currently working as a private caregiver, specializing in child care, senior care, and household assistance. As a proud mother, I have a deep love for being around children of all ages, from newborns and infants to toddlers and older kids, including twins! I find joy in engaging with them through various activities such as crafts, singing, playing and reading bedtime stories. In addition to child care, I have experience as a household assistant. I can help with cooking, cleaning, and running errands, ensuring that your home runs smoothly while you focus on other important tasks. My experience with caregiving extends beyond children. I have taken care of my own grandmother and parents, so I am comfortable and compassionate when it comes to senior care. I can assist with transportation to appointments and provide companionship to ensure that your loved ones feel supported and engaged. Please note that I am allergic to cats and dogs, so I would need to work in a pet-free environment. I look forward to the opportunity to work with your family and provide the care and support you need! Warm regards, Leigh

"We absolutely LOVE Isa — our family was so fortunate to have found her through UrbanSitter. I'm a first-time mom, and it took me a long time to find a full-time nanny I could trust to care for our sweet infant boy. Our boy connected with her immediately, and we couldn't have asked for anyone else to care for him. Her calming presence was also perfect for parents like us who work from home. We feel so lucky UrbanSitter helped us find someone who has truly become a part of our family."

"I was so stressed about finding a part-time nanny for my 14-month-old son, who has moderate separation anxiety and hadn't been left with anyone but family before, but we were both immediately at ease in Buhay's presence. Her empathy and commitment to understanding child development are apparent in every interaction I've witnessed between her and my toddler. I feel very lucky to have found her."

"Erna watched our now 5 year old daughter and 3 year old son for a few years. She is punctual, responsible, honest, and playful. What we appreciated most was that she was thoughtful in ensuring that we had a little break; for example, when the kids were clingy, she was able to divert their attention with games or songs or walks to the park. We felt very comfortable leaving our kids with Erna because of her caring nature and experience that spans a decade (including being a live-in nanny)."
