Ainsley $20 per hour for 1 child

I have been working with children for about 8 years now. I started off volunteering in my home church nursery with 1-2 year olds, I did this for about 3 years! I also while in high school worked at a YMCA as a summer camp counselor and also working in their afterschool childcare program! I also spent 3 years in college working for a babysitting referral company in Tampa! Throughout my time with this agency I worked with many different families doing both occasional/one time sitting jobs while also nannying!

Hi! My name is Kayla. I've spent the last ten years caring for children of all ages. Whether it's infants, toddlers, or teenagers, I'm extremely comfortable around kids and willing to learn and adapt to best care for your child or children! When it comes to taking care of your child, I enjoy outdoor adventures in the park, reading books, and baking sweet treats (with your permission, of course). My goal is to ensure your child stays happy and comfortable while you're away! I currently work part-time, which gives me a flexible schedule. I'm usually available early mornings, midday, and late nights, and I can accept last minute bookings. I look forward to meeting you and your loved ones!

“Kayla was early, giving us time to review instructions, answer any questions. Both minis took to her quickly. My 4 year old wanted to give her 100 stars, he looks forward to seeing her again.”

Hi. My name is Jaki and I'm living in Rancho Cucamonga. I am offering child care. I love being a babysitter and spend time with kids. I have been watching infants, toddlers, and kids (including triplets) since I was almost 20 years old. I have experience caring for children and creating a safe, calm, and organized environment. I follow daily routines such as nap time and meal schedules, and I keep play areas and baby items like bottles clean and organized. I also engage in early stimulation activities, playtime, and walks to support development, and I can assist with outings, playdates, and transportation as needed.

“Jaki has been working with our son for 3 weeks, and she does such a great job with him. She's done a great job helping us introduce him to solid food and is supporting him learning how to stand up and crawl. He has the biggest smile on his face whenever she walks in the door. We will continue to book with Jaki as long as she's available :)”

Hi everyone I’m Jocelyn is look forward to offering my services of child care, household services if needed as well as pet care. I’m the oldest of four siblings, and growing up caring for my brothers and sisters taught me patience, responsibility, and how rewarding it is to support children as they grow. I have experience with children of all ages whether that is an infant, toddler, or kid. I’ve also helped care for my younger cousins which has also helped me gain experience with kids of different ages and personalities. I truly love children and have a soft spot for them. I think children are very smart and curious, and just need patience, understanding, and someone open minded to guide them and listen. I also worked at a kids club in a gym, where I cared for multiple children at once. This taught me how to manage groups safely, keep them engaged, and ensure each child felt seen and supported. Along with my experience with children, I’ve grown up around animals. My family had three dogs and a cat, so I’m very familiar with caring for pets and understand how loving and important they are in a family. I enjoy spending time with animals, giving them attention, and making sure they feel safe and happy. I’m a caring, gentle, and dependable person who treats others like my own family. I take pride in creating a safe, nurturing, and positive environment, whether helping with homework, planning little fun activities, or looking after pets. I’m excited to meet your family and provide the support and care that you may need.
