sabian $20 per hour for 1 child

My experience working with young people is mostly across two different fields. I have experience with foster care and homelessness when I was younger and from the age of 16 to current day (although I do it less now) I have worked with young people experiencing foster care providing trainings, education, and public speaking opportunities pertaining to policy and legislative advocacy. I also over the years have combined about 5-6 years of experience working with young people in environments such as schools, boys and girls club, various day camps, and babysitting for my auntie. I love working with kiddos, and am more than capable of working with groups of them as well as taking care of them one on one. I think of myself as a fun and funny guy. I think there's just as much to learn from children as there is to teach them. I am confident in my ability to provide a safe and fun environment for whomever I'm working with. I also have recent a full background check for a previotjob I had working with young people in foster care before I moved to Seattle that I'd be happy to provide.

Booked by 1 family in Mercer Island, WA

Hi families. My name is Julieth.I am a Spanish and English teacher. I have been working with my current family for 2 years, but they only need my help during the afternoons. I want to cover my mornings; however, I am open to work after 6pm and occasional weekends. I have had the opportunity to work with children of various ages, from infants to pre-teens. I genuinely enjoy engaging with children, fostering their growth, and creating a positive and fun atmosphere for them to thrive in. It brings me great joy to be a part of their journey and contribute to their overall development. I understand the importance of providing a structured yet flexible routine that aligns with the unique needs and interests of each child. Whether it's organizing stimulating activities, assisting with homework, or preparing nutritious meals, I strive to create an environment that promotes learning, creativity, and emotional well-being. My skill set includes: · Extensive experience in providing compassionate and responsible care for children of all ages. · Proficient in creating and implementing age-appropriate activities to stimulate cognitive, physical, and emotional development. · Excellent understanding of child development stages, including milestones and appropriate behavior management techniques. · Strong communication skills to establish open and honest communication with both children and parents. · Ability to maintain a safe and clean environment, prioritize safety measures, and handle emergency situations calmly and efficiently. · Willingness to help with light household tasks to support the smooth functioning of the household. I would be delighted to have the opportunity to meet with you and your family to discuss how I can contribute to your children's well-being and growth.

“Julieth is a caring, intelligent, and one of the most responsible people that we have had the pleasure of working with. She is energetic and passionate, which makes her a perfect candidate for our toddler and while we we find it hard to manage a toddler and a baby together, it comes pretty natural to her. Adding to this, she figures out her back ups and saves us a bunch of time, when we need someone on short notice.”

"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."

"Caitlin has been such a lifesaver for our family. We hired Caitlin to help with the after school routine. The kids took to her instantly. She does it all - school pick ups, dinners, baths, lunch making, clean up, etc. She has really helped make a busy time so much easier for us."
