Hi! I’m a college student going into my second year with years of experience caring for children in both home and educational settings. I’ve worked with kids of all ages, from toddlers to school-aged children, and I truly enjoy building strong, positive relationships with every child I work with. I'm kind, respectful, and reliable, and I always bring patience and creativity into my care. Whether it’s helping with homework, following routines, or planning fun activities, I focus on creating a safe and supportive environment where kids can feel comfortable and thrive!

Tim $30 per hour for 1 child

I *love* kids, from the awesome, fun 2 year olds to the teenagers that just need an adult in the room to make sure they're being cool with their social media ... I'm your guy for that. :) I'm a 53 year old father of two daughters, 19 and 13. I'm just a tech guy affected by layoffs and looking to "fill some holes in my budget," and find helping with kids is a great way to do that. Watching after the kids is fun and I get to help out some parents that need a break/some assistance. I remember being in that position when my kids were younger: wanting to go out, needing to take care of something, and not having someone trusted and reliable to count on. I can be your go-to here. I also don't mind some light housekeeping like laundry and dishes. I know I'd love to come back to my place just a little bit nicer than it was when I went out ... or at least don't have to take care of the kids' and babysitter's dishes or that wet load left in the washer before you left :) I think you'll like working with me and feel comfortable you can trust me with your kiddos.

"We absolutely LOVE Isa — our family was so fortunate to have found her through UrbanSitter. I'm a first-time mom, and it took me a long time to find a full-time nanny I could trust to care for our sweet infant boy. Our boy connected with her immediately, and we couldn't have asked for anyone else to care for him. Her calming presence was also perfect for parents like us who work from home. We feel so lucky UrbanSitter helped us find someone who has truly become a part of our family."

"I was so stressed about finding a part-time nanny for my 14-month-old son, who has moderate separation anxiety and hadn't been left with anyone but family before, but we were both immediately at ease in Buhay's presence. Her empathy and commitment to understanding child development are apparent in every interaction I've witnessed between her and my toddler. I feel very lucky to have found her."

photo of quoted parent Eric

"Erna watched our now 5 year old daughter and 3 year old son for a few years. She is punctual, responsible, honest, and playful. What we appreciated most was that she was thoughtful in ensuring that we had a little break; for example, when the kids were clingy, she was able to divert their attention with games or songs or walks to the park. We felt very comfortable leaving our kids with Erna because of her caring nature and experience that spans a decade (including being a live-in nanny)."
