Clara María $25 per hour for 1 child

Hi, I’m Clara. Taking care of children has always come naturally to me. I helped raise my grandson from the day he was born until now, he’s seven, and being part of his life has taught me so much about patience, creativity, and how every stage brings something special. I’ve also cared for newborns and toddlers, giving them lots of attention, helping them start talking, and teaching simple Spanish words through play, songs, and stories. I love seeing how quickly they pick things up when learning feels fun. Cooking is one of my favorite ways to show care. I enjoy making healthy, homemade meals with Latin American flavor, rice, soups, arepas, and sweet plantains that kids usually love. Families tell me I bring calm energy and warmth into their homes. I believe children grow best when they feel loved, safe, and understood.

Hi! I prefer to go by Jasper. I try to wear a mask to all my appointments. I have a vehicle, I cannot transport individuals. I have worked with young and old individuals needing specialized supports and behavioral needs for the last 6 years. I have previously/currently practice ABA therapy in schools, clinic, and home settings while working under a contracted company for the last 3 almost 4 years now. Before that I worked as a day support staff and have worked in home care settings as a caregiver. I am good making sure prepared food is able to get to the child(ren) on a schedule or when asked for and being fed to them if needed. I enjoy providing pretend play or engaging with preferred activities in natural settings while providing naturalistic support. I understand and know some basic asl. I enjoy working with nonverbal individuals and can help support using an AAC device/pictures if those are provided. I am aware of potty routines for small children, I would like individualized communication over what that looks like in your home. Willing to work with cultural differences, please make me aware of how you run your household. I am good with light housekeeping, doing laundry/folding laundry/putting away, refilling food/water dishes, and letting pets out on a schedule. please let me know what this looks like for you!

"Johanna is AMAZING! My two boys love her - she does everything from amazing arts & crafts, to helping with homework, to getting them playing outside! She also drives them and does everything involved with after school activities: packing snacks, getting the right gear, etc."

"When we hired Amani, we felt like we hit the jackpot. We were very lucky to find her on UrbanSitter at the beginning of school year. She was picking up kids from school, taking them to afternoon activities, helping them with assignments. She prepped food for them, helped organize their closets and keep their spaces neat and orderly. We would hire her again in a heartbeat."

"Caitlin has been such a lifesaver for our family. We hired Caitlin to help with the after school routine. The kids took to her instantly. She does it all - school pick ups, dinners, baths, lunch making, clean up, etc. She has really helped make a busy time so much easier for us."
