$18 per hour for 1 child

Hi I’m Elsa, and I’m Hispanic with a lifelong love for caring for children. Since my early teens, I’ve helped my grandmother care for many little ones—family, friends, and neighbors—gaining experience with diaper changes, feedings, and playtime. I recently had the joy of babysitting a 2-year-old boy while his mom worked from home. My responsibilities included diaper changes, preparing simple meals, light housekeeping, and playtime. I became very close to him, watching him grow from crawling to walking independently after physical therapy—it was truly a special experience. We’d go outside on sunny days with his little car, play with his blue ball and blocks, and wind down together with his favorite shows before naps. I also accompanied his mom on several doctor’s visits, helping out wherever I could. I’ve also cared for a 1-year-old girl and a 3-year-old boy. We’d often take walks to the nearby park where the older boy loved playing hide-and-seek. I bottle-fed the baby girl, rocked her to sleep, and made sure both children felt safe and cared for while her mom did her long nurse shifts. In addition to babysitting, I help my mom raise my energetic 1.5-year-old baby brother. He’s always on the move, loves to climb, dance to music, and pull me by the hand to play with his cars. Taking care of him has taught me patience, attentiveness, and how to manage the unexpected—which, with toddlers, happens often! I genuinely love being around children and form strong bonds with every child I care for. I’m confident in my ability to keep your little ones safe, entertained, and nurtured. Thank you for considering me! We can negotiate hourly rate :)
