“Shelley did a terrific job taking care of our 3.5 year old. She was great about jumping right in to feed her dinner, play games, read to her, and give her a bath before bed. She was very professional, communicative, and puntctual. I highly recommend her to other families, and we would love to have her come back to take care of our daughter.”

“She's amazing!✨️”
I am energetic, friendly, easy-going yet reliable and responsible. Love kids of all ages & they tend to love me. I have current extensive experience caring for children 0-12Y. I add value by being medically trained in pediatrics, being bilingual (English/Russian), engaging kids in fun learning via play and helping around the house (time permitting).
“Very professional and prompt, appreciative of Valerie stepping in last minute when our other sitter fell through for backup care for our sick one year old. Appreciate her help with other small tasks while kiddo was napping. ”
My name is Tassia. I'm a Portuguese/ English/ Spanish speaker nanny, 36 years old. I'm looking for one-time job, date night jobs. I have been working with children since I was 15 years old. My specialty is infants and toddlers but I'm also good with teenagers. I'm CPR and First Aid certified. I'm fully vaccinated Covid. Thank you for taking time to read my profile, fell free to send me message. Talk to you soon!
“If the app allows 10 stars rating I would choose that for Tassia! She’s kind, fun, very aware of the surroundings and knows what to do as soon as she stepped foot inside. We knew we can trust her with our kid after the first booking. She’s great with our 4 years old and also newborn. She is also a great artist that my son cannot stop talking about her drawings. If you need someone love the children more than just a job-Tassia is the one! Thank you Tassia!”

"We were incredibly grateful that Maya was able to help us out with a last-minute childcare emergency. She matched our 9-year-old's energy with arts & crafts, some quiet reading, and a walk around the neighborhood. We'd have Maya back in a heartbeat!"
