There isn’t a single “best” bank for children in Sri Lanka — the right choice depends on the child’s age and what you care about (low minimum deposit, rewards/gifts, insurance/benefits, teen debit-card & digital controls, branch/ATM access). Below are the banks most parents consider, with the key reasons to choose each.

Top options (what they offer)

• HNB — Singithi (newborn → 12) / Singithi Lama: low minimums, birthday gifts, standing‑order protection (insurance that continues a monthly standing order if a parent dies), scholarship rewards. Good for long‑term saving and parental protection. (hnb.net)
• Commercial Bank — Flash Fam / Teen digital account: focused on tech‑savvy teens, debit card, parental controls, budgeting & savings‑goal tools and a fully digital app. Best if you want your teen to learn digital banking safely. (combank.lk)
• Bank of Ceylon (BOC) — Ran Kekulu / Haritha Kekulu: higher bonus interest vs regular savings, medical/life insurance benefits and scholarship schemes. Strong option if you want insurance + rewards attached to the child account. (boc.lk)
• Sampath Bank — Pubudu: popular gift‑voucher reward scheme (vouchers increase with balance); motivates kids with tangible rewards for saving. Good if rewards/gifts matter. (dailymirror.lk)
• Nations Trust Bank — Nations Kidz & Kidz Investment Plan: kid‑oriented rewards, gifts and a dedicated investment plan with a fixed/guaranteed rate option for longer terms. Good if you want a formal investment plan for a specific future date. (nationstrust.com)

Quick practical checklist to choose

• Minimum opening deposit and monthly requirements (important for newborns).
• Interest / bonus interest for minor accounts.
• Fees and ATM/card access (teens).
• Extras: gift/reward schemes, birthday gifts, scholarship incentives, medical/life cover.
• Digital/parental controls if you want your child to have a debit card or app.
• Branch/ATM coverage where you live.

Quick picks by priority

• Newborn / very low balance: choose an account with a very low minimum and gifting (People’s Bank Isuru Udana or HNB newborn product are commonly used).
• Long‑term saving + insurance: BOC Ran Kekulu or HNB Singithi (insurance + scholarships).
• Motivate kids with rewards: Sampath Pubudu or Nations Kidz.
• Teen learning independence / digital skills: Commercial Bank Flash Fam Teen.

If you want, tell me the child’s age and which features matter most (lowest minimum, gifts, insurance, digital card), and I’ll recommend the single best account for that situation and include branch/contact info and the exact opening requirements.
