Hi my name is Leann and I have been officially nannying as a career for almost 3 years now. I have been a pre k teacher, kindergarten, and first grade teacher for over 5 years in addition to the three years of Nannying. Before that I have babysat many times when I used to live in Georgia. Total time, 8-9 years working in childcare/education. (Part-time work only) I have an printing and graphics degree, so I’m well-versed in arts and crafts. I also have a BBA. I have been a teacher for six years and I also am an excellent cook and professional baker. I taught English for four years in China. The ages are 1-13 years old. I taught baking and science classes as well. I’m very familiar with other cultures and I can speak Chinese as well. I love kids and finding out their interest. I can create fun activities and games. I also have a contact to sign once the employer agrees before working as well. If you have any questions, then please let me know. Please contact me if you would like to know more. I have been an household manager and a tutor. Cooking and cleaning is second nature. I like keeping everything organized and clean. Thanks! I can’t wait to talk to you!

Hi, I’m Mavi! 😊 I have several years of hands-on experience caring for children of all ages, from newborns to school-aged kids. I currently work full-time with twin toddlers and also provide evening and weekend care for two other families. I’m passionate about supporting children’s growth and love creating a safe, fun, and nurturing environment where they can learn, explore, and feel truly supported 💛✨ Although I’m new to this app, having just created my account, I already have plenty of experience caring for children. I would love the chance to help out as your babysitter! Your family seems so warm and special, and I truly believe I’d be a perfect match. I have a natural gift for connecting with children. I’m patient, loving, and always bring a mix of fun and responsibility to every moment. It would make me so happy to ensure your kids feel safe, happy, and understood. I look forward to hearing from you and hopefully getting the opportunity to know your amazing family better soon! ❤️🥰

Hi, I’m MJ, and I’m 29 years old. I have many years of childcare experience and have been caring for children since I was 15, working with newborns, infants, toddlers, and school-age kids. Right now, I’m currently nannying for two children, ages 6 and 8, and I also provide backup care by covering shifts for a full-time nanny when needed. This has given me strong experience adapting quickly to different family routines, school schedules, activities, and household needs. In the past, I also cared for a baby from 3 months to 12 months old, so I’m very comfortable with infant care, including feeding, diaper changes, nap schedules, and creating a safe, nurturing environment. I enjoy engaging children through play, reading, educational activities, tutoring, and helping with routines such as swimming lessons. In addition to childcare, I can assist with light household tasks, organizing, errands, and pet care. I’m a dog owner myself, so I’m very comfortable caring for pets as part of supporting a busy household.

“MJ is so kind & my boys had nothing but great things to say about her ! I would definitely hire her again! 10 out of 10 I really recommend hiring MJ for your family ! ”

OOH TOODLES!! Hello there, I am a local childcare provider with a TON of child care experience. Over the last 13 years I have gained childcare experience ranging from fostering infants to tutoring elementary students, being a nanny, baby sitting, and various other childcare positions (a majority of my experience is with 0-4 years). In my spare time I enjoy traveling, self educating on foreign languages and countries, and creating memories. It is ideal for me to establish with a family who is seeking long term childcare. I am willing to vacation with the family as well as drop off/pick up if age appropriate. I am experienced with light house work for child as well as meal prep and pet friendly. CPR, First aid, blood borne pathogen certified, Valid Driver's license, continuing Early childhood Education credits, experience with sleep training. Availability: Full time shifts Monday - Friday starting as early as 5:00 am ending no later then 5:00 pm (No more then 10 OT hours)

“We had a really positive experience with Princess! She helped us out in when we were in a bind with our approaching 5 & 2 year old kiddos. She brings a very calm & positive energy. She came prepared with bubbles and other fun activities for them but asked me what I was okay with before doing anything She kept the kids active and outdoors most of the day which was AMAZING to have them burn off energy. The kids acclimated to her super well & by the time it was time to say goodbye, my son made a comment that he wished she could stay forever (which is not something he’s ever said to any prior sitters we’ve had) She was punctual, and seems to genuinely love children; which our family could feel Look forward to having her back! ”

"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)."
