Saving
Saving for a child means deciding who owns the money at eighteen
The account choice looks like a question about interest rates and is actually a question about control.

These are listed in the order worth acting on, which with saving for children is not the order they are usually presented in.
What matters most
- Accounts held in a child's name usually transfer to them at the age of majority.
- Accounts in a parent's name keep control but may be taxed differently.
- Rules on tax, access and ownership vary substantially by country.
The fork in the decision
Money can be saved in the child's name, in which case it is legally theirs and generally becomes accessible at the age of majority. Or it can be saved in an adult's name and earmarked for the child, in which case the adult retains control and the tax treatment follows them. The first offers tax advantages in many systems and no control at eighteen; the second offers control and usually no shelter.
Deciding which trade-off you want is the whole decision, and the interest rate is secondary to it.
What happens at the age of majority
In most jurisdictions, funds in a child's account become theirs to use as they choose on reaching majority, with no requirement to consult anyone. Parents are frequently surprised by this, having thought of the money as earmarked for education or a property deposit. Some products lock the money until a specified age, which removes flexibility for genuine need before then as well.
Over a full year, if the possibility of an eighteen-year-old spending it differently would be unacceptable, the money should not be in their name.
Tax treatment differs and can rebound
Many countries offer tax-free or tax-advantaged children's savings, sometimes with annual limits and sometimes with government contributions. Several also have anti-avoidance rules under which interest on money gifted by a parent, above a threshold, is taxed as the parent's income. Gifts from grandparents and others are often treated differently from gifts from parents in exactly this respect.
These rules are detailed and change, so they need checking with your national tax authority rather than assuming.
Long horizons argue for more than cash
A newborn has an eighteen-year horizon, which is long enough that cash-only saving faces meaningful erosion of purchasing power. Many countries offer child-specific investment accounts alongside cash ones, with the same ownership consequences.
Whether that is appropriate depends on when the money is needed and your capacity to accept fluctuation, and it warrants regulated advice. A common structure is longer-horizon money invested and near-term money in cash, with the mix shifting as the child approaches the date.
Regular small amounts do the work
Over an eighteen-year horizon, a modest monthly contribution accumulates substantially more than an occasional lump sum, because of both total contributions and time. Setting a standing order at birth and increasing it occasionally is the version of this that actually happens.
In numbers, directing gifts from relatives into the same account rather than into toys is worth agreeing explicitly with them. The amounts feel too small to matter in the first years, which is exactly when they have the most time to compound.
Rates, thresholds and rules differ by country and change often — check current figures before acting.
Teaching alongside the balance
A visible account the child can see and eventually manage does more for their financial capability than a hidden one they receive at eighteen. Some families stage access deliberately — a small accessible account plus a locked long-term one — so the learning happens before the larger sum arrives.
For most households, talking about what the money is for, well before majority, is what makes the eighteenth birthday less of a gamble. None of this is a substitute for local legal and tax advice where the sums involved are significant.

The takeaway
Choose the ownership first and the account second. At eighteen the name on the account is what decides.
The decision is rarely about picking the best option — it is about avoiding the expensive one.
Questions readers ask
Can I stop my child accessing the money at eighteen?
Generally not if it is held in their name. Where control matters, the money usually needs to be held in an adult's name or a formal trust, which has its own tax and legal consequences locally.
Are children's savings accounts tax free?
In some countries, up to limits, and often with rules about who gifted the money. Check your national tax authority, because the thresholds and anti-avoidance rules differ.
