Our nannies range in age and gender, each of them with extensive childcare experience. Every nanny undergoes an intensive selection process of interviews, certifications, background checks and experience all mandatory for hire. Health, happiness and activity are integral to our company as far as the children are concerned. Parents and children alike can count on healthy, food options and special attention to any dietary requests.  The children are kept excitedly active alongside their caretakers without the assistance of iPad games or prolonged screen time. Our staff guarantees exact matches.  Parents can view each candidate’s online profile and schedule interviews with potential employees, all overseen by Four O Six Nannies.


A full or part time nanny may not be necessary and we understand. In addition to nannies, we offer professional tutoring services, swim instructors.  Unlike most nanny agencies, we offer services for every schedule. There is no minimum time commitment for a Four O Six Nanny. Regardless of the timetable, the same amount of care is taken, ensuring absolutely perfect matches.  Children will never be herded from school to home and thrown the remote, a juice box and a cheese stick. We provide a new level of care that integrates healthy lifestyle choices with intensive attention to each child’s interests.  


Nannies are friends, confidants, educators, and playmates.  The nannies, tutors, and instructors in this agency go the extra mile to ensure quality childcare for busy parents. If each candidate’s resume isn’t enough to convince parents to give us a chance, a conversation with our owner Karissa Erickson will be. 



"I can't say enough good things about Karissa and Four O Six Nannies. From their reliability, experience, maturity, and capabilities. I first hired Karissa to house-sit/dog-sit, which she was exemplary at (even going to great lengths to retrieve a dog toy from the roof) and subsequently hired her as a nanny for our infant. My daughter is now five years old and still begs to have Karissa watch her. Karissa is always timely, joyous, and dependable.  From day one, I felt comfortable leaving my daughter with her. She engages with my daughter, is creative in her activities, takes her to the park, cooks meals and enforces our family's rules. She’s even attended my daughter’s dance recital, just because! Most importantly, she communicates extremely well. I have entrusted her to drive my child to swim lessons and other extracurriculars. I highly recommend Karissa and Four O Six Nannies to anyone who desires the best in child care for their family."

"Karissa is one of the most engaged, compassionate, aware, and focused caregivers we've had for our girls. Our twin girls just turned 2 and we had recently moved back to Bozeman after several years away when Karissa became our full time nanny. Under her care they have explored local parks and museums, "helped" to bake healthful treats and snacks, worked on toddler skills like sharing, patience, and potty training, developed a love for arts and crafts, and most of all continued to be supported as they grow into children. I've been most impressed with how seriously Karissa takes her role in a family as a gentle and steady guide for the children she looks after. Her high bar for professionalism, communication, and care is the cornerstone of Four O Six Nannies. I would highly recommend her service to families looking for quality childcare."

"Karissa Erickson has worked as a live in Nanny for my family of 5 for the past two years in Big Sky, MT. There is no doubt that she is hands down the best around.  Aside from being sweet and easy to get along with, she is amazing with kids.  Karissa can adapt to many personalties and age ranges.  We had house guests come to visit and she watched all 6 kids, ranging in age from 3-8.  Parents can rest assure that there children will have a ton of fun and be well taken care of. Karissa is a jack of all trades; a true gem.  Our family highly recommends Karissa Erickson and Four O Six Nannies!"

Our family of six uses Four O Six Nannies for occasional babysitting. We send them an e-mail of the dates that we need coverage and they quickly respond and book a sitter immediately. The babysitters are always wonderful, show up on time and are ready to play and care for our children. When we return the children are asleep in bed and the house is cleaner than we left it. They are professional and always reliable. We highly recommend Four O Six!

Solves the I-can't-find-a-sitter-dilemma! Every single one of the nannies we've had from Four O Six Nannies has been knowledgable, experienced, and kind. We've had a variety of care needs for our infant and 5 year old, from days at Big Sky to evenings out nights in Bozeman and Karissa always sends us someone great.
