Booked by 2 families in Mercer Island, WA
Hello, my name is Hattie! I am a graduate from Western Washington University and recently moved to the Seattle area. I offer child care, pet care, and housekeeping services. I have five years of experience caring for toddlers and school age children, and two years of experience in infant care. However, I have been a sitter for friends and family now and then for about eight years. I love children and specifically enjoy crafting, cooking, and reading with them. I have past experience giving music lessons and tutoring so I am happy to incorporate that into child care as well! Additionally, I love pets and have extensive experience with dog and cat-sitting. I am able to board them in my home, care for them in your home, and/or do daily visits. I have experience with all breeds, so no pet is out of the question. Finally, I can offer household services, such as cleaning, cooking, laundry, running errands, general house sitting, and yard work!
“Hattie was responsive, on time, very professional and great with my kids. She played with them the entire time and kept them entertained. My kids warmed up to her immediately and even my son, who is in a VERY clingy mommy stage (20 months old), stayed with her. She had no problem with both my son and 3 year old daughter. ”
