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.

"Johanna is AMAZING! My two boys love her - she does everything from amazing arts & crafts, to helping with homework, to getting them playing outside! She also drives them and does everything involved with after school activities: packing snacks, getting the right gear, etc."

"When we hired Amani, we felt like we hit the jackpot. We were very lucky to find her on UrbanSitter at the beginning of school year. She was picking up kids from school, taking them to afternoon activities, helping them with assignments. She prepped food for them, helped organize their closets and keep their spaces neat and orderly. We would hire her again in a heartbeat."
