Hello, my life has always revolved around children. I worked with my local school district for over 20 years as a Chid Aide. The program was designed to improve a child's self-esteem and improve comfortability in a social setting. This was done through interactive play sessions where a child can truly be themselves. Apart from raising my own three children, I have also worked at a daycare providing a safe and educational environment for up to 12 children. Nutritional cooking is also a big part of my life and something I enjoy sharing. My passion is caring for children in fun, educational, musical, and artistic ways.

“Such a great caretaker. Jumped in on short notice to help with my 1y and 5y and was great with both. I felt at ease immediately with Alexandra in our house and hope to work with her again.”

Hi my name is Olue and i am an amazing mother of 2 boys who are 9 and 13yr. I am a college graduate. I enjoy working with children and have been watching kids for over 10yrs. I am experienced in Nanny shares and 1 child care also. My responsibilities are to make sure that i work as a team with parents, feeding, teaching, nurturing, Loving and creating a safe space for a child but most importantly being gentle. Fully vaccinated including Tdap. I already work for a Family part time and have been going 9 months now. I honestly am a great nanny who doesn’t mind helping around the house so parents can come home and spend time with their child. I am a 100% ok with families who have pets.

“Olue was simply amazing. She has a warm, calm presence that both of my boys responded to immediately. My two-year-old is very attached to me, and while he needed a few minutes to warm up, he quickly felt comfortable and connected with Olue — which says so much about her natural ability with children. She was engaging and attentive, met my son exactly where he was, and followed his lead based on his interests and energy level. I felt completely at ease leaving him in her care and would wholeheartedly recommend her to any family looking for someone trustworthy, nurturing, and genuinely wonderful with kids.”

Hi parents! My name is Ligia. If you’re looking for a reliable, responsible, respectful, and energetic babysitter, I’d be happy to help. I have over five years of experience caring for children of different ages. I understand how important it is to trust someone with your child. I focus on clear communication, following family guidelines, and making sure both parents and kids feel comfortable. I’m more than happy to do an interview before the job or answer any questions you may have. I enjoy doing different activities with kids such as playing, reading, crafts, and staying active.

“Ligia was wonderful with our little one! She is energetic, engaging, and caring. My little one really enjoyed playing with her and didn't want her to leave at the end :) Ligia is also professional and communicative. Will definitely work with Ligia again!”
