Below are Sri Lanka hotels and resorts (by region) that advertise on-site babysitting, kids’ clubs or child‑minding services. I’ve included one short note about the service and a source link for each — please check with the hotel directly before booking to confirm current availability, hours, age limits and charges.

Colombo / West Coast

• Shangri‑La, Colombo — offers childcare / babysitting services at the hotel. (Expedia.co.in)
• Galle Face Hotel (Colombo) — listed by major booking sites as offering babysitting/childcare. (Expedia.co.in)
• Cinnamon Grand / Cinnamon Lakeside Colombo — part of Cinnamon Hotels group, which promotes kids’ club and family facilities at their properties. (Confirm which Cinnamon property you plan to stay at for exact childcare options.) (cinnamonhotels.com)

South Coast (Galle / Weligama / Mirissa / Tangalle / Bentota)

• Cape Weligama — family-friendly resort with kids’ activities and childcare options (property advertises kids’ club/children’s programmes; confirm babysitting availability). (Anantara.com)
• Anantara Peace Haven Tangalle — Joli Kids’ & Teens’ Club and staff who run supervised kids’ activities; guests report availability of nanny/child‑minding on request. (Anantara.com)
• NH Bentota Ceysands (Bentota) — guest reviews and hotel pages note babysitting / kids’ club / daycare options. (Tripadvisor.com)

Cultural Triangle / Hill Country

• Heritance Kandalama (Dambulla / Sigiriya area) — explicitly lists “babysitting” (bookable at reception; request at least 24 hours prior). (heritancehotels.com)
• Uga Escapes properties (examples: Uga Ulagalla / Ulagalla) — Uga group hotels commonly offer family services and child‑minding across properties; check the specific Uga property you plan to use. (Confirm with the property.) (Anantara.com)

Chain / Multiple locations and booking sites

• Jetwing Hotels (several Jetwing properties) — Jetwing properties often provide child‑minding services or have sister hotels with professional childcare centres; some individual Jetwing Hotels explicitly accept babysitting requests. (Tripadvisor.com)
• Many hotels listed on major travel sites (Expedia) in Colombo and elsewhere are flagged as offering childcare or babysitting (use filters “hotels with childcare” / “babysitting services” to find current options and reviews). (Expedia.com)

Notes and tips

• Services vary widely: some properties run a kids’ club with supervised activities (hours, age ranges), others provide on‑request babysitters or nannies (may be hotel staff or third‑party, usually charged hourly). Always confirm age limits, staff qualifications (e.g., first aid), hours, lead times for booking (many require 24+ hours’ notice) and extra fees. (heritancehotels.com)
• If you’d like, I can: a) check a specific hotel or town for up‑to‑date childcare availability and contact details, or b) search for family‑friendly hotels in a particular Sri Lankan destination (Colombo, Galle, Bentota, Kandy, Sigiriya, Tangalle, etc.) and return a short list with current phone/email and the exact childcare offering. (If you want that, tell me which city or hotel names to check.)

Would you like me to verify any of these hotels now (I can contact the hotel pages / official sites and return confirmed details for specific dates)?
