Booked by 1 family in Mercer Island, WA

Hello, I am a retired social worker, who has experience raising two adults and two grandchildren. Most recently, I was employed with a family with a 9 year old daughter. I worked three afternoons a week. I would pick her up at school in the unversity district , drive her home to Edmonds. Unless she had after school activity or tutoring, when home I would perpare a snack, look at her homework. At time she needed encouragement to complete her homework, I was able to help her with getting it done before dinner. One or two days a week she attended math toutering, one other days she would have swimming or gymantic. I would wait for her until her activity, and then return her home. Most evening i stays with her until 6 or 7 pm. If her parents were working late, I would prepare her dinner and hang out with her until her parents retiurned. If she was bored we would plays games or watch a parent approved show. At time I would be flexiable and stay later or changes schedules depends on the parents needs. vess she had an activiety she needed to attend. She had several extra the granddaughter full time nanny, from ages 6 months until she was 3. In addition to my life experiences with infants and children, part of my education, was courses in infant mental health and child development. I would like to share my calm, easygoing, nurturing grandmother personality with other families. After years of raising children, while living busy lives, I truly understand the need for a safe,secure and nurturing environment for children best development. In addition, I understand how difficult it can be to raise children, without help..I would love to meet your family and see if I can be an asset to your household I will look forward to hearing from you. Kathleen

Booked by 6 families in Mercer Island, WA

Hi, my name is Fiona. Im 24 years old, I am looking for something long term and full time/part time. Occasional date nights too:) In previous years I took a class called child development and learned basic early child development course work. While in that class I got the opportunity to work with kids ages 3-6 at my schools preschool, created lessons, and fun activities for them to do. By doing that I am now child development certified. I also have worked a day camp during the summer, in past years, working with grade school aged kids. I started nannying about 5 1/2 years ago, taking care of family friends and so on. I love being around kids and creating fun activities for them to do, such as arts and crafts, like making slime and etc. I also have been a lifeguard in the past and so I am CPR and First Aid certified. I hope to be in consideration and to meet you and your family! :)

“Fiona is a very punctual and sweet sitter. She’s very involved and my child loves her.”

"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)."
