Here are well-known hotels in Singapore that advertise child‑friendly / child‑safe pool features (separate shallow pools, splash pads, water slides, lifeguards or supervised kids sessions). I’ve listed the key child‑safety feature(s) and one or two sources you can check for details and current rules:

• Shangri‑La’s Rasa Sentosa (Sentosa) — children’s pool, splash pad, 3 water slides; life jackets available and lifeguard presence reported. (shangri-la.com)
• Shangri‑La Singapore (Orchard) — “Splash” family water playground with shallow wading pools and multiple water‑play areas designed for kids. (shangri-la.com)
• Marina Bay Sands — hotel rooftop infinity pool has a family section and a small children’s/wading area; the hotel runs supervised kids sessions (“Infinity Splashers”) with dedicated lifeguards/instructors. (Pool access rules and child hours vary; confirm at check‑in.) (marinabaysands.com)
• Hard Rock Hotel (Resorts World Sentosa) — large family pool area with an artificial (synthetic) beach, shallow play areas, water slide and splash features suitable for kids. (innpix.com)
• Festive Hotel (Resorts World Sentosa) — family/kids pool areas including a baby pool and wet play area (splash pad). Guests often use nearby Hard Rock family facilities as well. (innpix.com)
• Village Hotel Sentosa — multiple themed pools including a Children’s Play Pool (shallow wading, slides and water features), Lazy River and family/adventure pools. (villagehotels.asia)
• W Singapore – Sentosa Cove — large WET Deck pool with a kiddie area and waterslide; popular with families (note: some W pool areas may have “no lifeguard on duty” policies — check before swim). (singaporemotherhood.com)
• Capella Singapore (Sentosa) — multiple pools; the hotel states one pool is family‑friendly with a wading area suitable for children (some other pools are adults‑only). Guests report limited/no lifeguard coverage at certain pools — confirm with the hotel. (tripadvisor.com.sg)

Quick pool‑safety reminders (apply at any hotel):

• Always supervise young children within arm’s reach; don’t rely solely on “kids’ pools.”
• Ask the hotel whether lifeguards are on duty, pool depth(s), availability of life jackets/floats, and any age restrictions or scheduled children’s sessions.
• Check current pool hours and booking/slot rules (some hotels limit pool time per room or require advance booking).
• Pack or request sun protection (rash vests, sunscreen) and non‑slip footwear for wet decks.

If you want, I can (without booking) sort these by area (Sentosa vs. city), budget, or which explicitly list lifeguards and shallow depths — and include direct hotel pool‑policy links.
