The case for having a big family

When I tell people that I have five kids, they tend to say: "Lucky you". Roughly translated, that means: "What a show-off."

A generation back, large families were generally attributed to rejection of contraception; nowadays, they are considered to be a public declaration of a huge income, limitless energy and a selfish disregard for the future of the planet, to boot.

None of the above is true in my case, but I'm always rather feeble in putting the case for large families any more coherently than to say that I enjoy having lots of children, however expensive and tiring they can be.

Each throw of the genetic dice is a new adventure, a fascinating individual, another sometimes tiresome, usually loveable bundle of strengths and weaknesses. I didn't plan to have so many; I just couldn't bear to stop.

The point about big families is that they are more than the sum of their parts - they are a microcosm of society in which the members battle for attention and the best seat in the car. The squabbles are endless, and often intense, but at the end of the day (literally) everyone has to get on with one another, because they have to share the television remote control.

As such, I've always believed that large families are not just a selfish pleasure but beneficial for the country, even the world - but, until now, I've been short of ammunition for arguing my case.

A journalist's mission

I'm grateful, therefore, to Sky News television presenter Colin Brazier, who has spent the past five years assembling evidence that supports the idea that larger families are a good thing.

"We are so often told about the disadvantages of large families that we have lost sight of the hidden advantages," he says.

His mission began one day at the start of the Iraq war when, while embedded with the United States army, he heard a radio report claiming that the cost of bringing up a child had risen to £180,000 (Dh1.23 million).

At the time he didn't have the five children that he has now, but he was already aware that it was nonsense to suggest that it costs as much as the price of a family house to raise each child. By sharing bedrooms, baths and toys, he could see that each additional child in a large family worked out cheaper to raise than a child in a small family.

Nor did he feel it was fair to calculate that each child adds an additional 750 tons of carbon dioxide to the environment.

Blame it on the singles

"What about economies of scale?" he thought. "A four-person household uses half as much electricity, per capita, as a home for one. The people who are messing up the planet are the single people living alone in swanky apartments. Someone needs to rebut these nonsensical stories."

Since then he has not just gathered arguments for the defence, he has gone on the attack. Having condensed his research into an article for the think tank Civitas, he may need to don his flak jacket again, because the anti-natalists who advocate the benefits of a small family may not like what he has to say.

Nor may the Government. In Britain, we are penalised by higher taxes on people carriers and will soon have to pay through the nose for rubbish collections and water use. Private schools don't offer discounts for bulk buying, while state schools are abandoning sibling policies.

The result of such measures, combined with the constant scare stories about the cost of children, is that 90,000 people have fallen into a baby gap: they would like to have more children but don't dare. With the British birthrate currently standing at 1.7 per woman - well below replacement level - Brazier argues that there's no need for such restraint. It doesn't matter if you can't afford a large house.

Having several siblings is also a pointer to future mental health. Scions of large families stand a good chance of making a success of their marriages, because they are used to sharing. There is also safety in numbers from the pressure of ambitious, fussing parents whose tendency to hover like helicopters over their children's heads contributes, according to a recent Unicef survey, to British children being the most miserable in the developed world.

I'm as keen as the next mother for my children to be world-beaters, but with several children to compare I'm more realistic about their talents and don't have either the time or the resources to apply the mental thumbscrews. Mostly, I'm happy to settle for the children being whoever they happen to be, so long as they help with the washing-up.

What's missing in this country, according to Brazier, is a lobby to uphold the manifold benefits and interests of the large families. If he wants to start one, he can count me in.

Pros

Children from larger families get into fewer fights, and are better at making and keeping friends.

Through having siblings, children learn empathy, team playing, gratification deferment, time-management and how to resolve disputes.

Children with several siblings have lower rates of asthma, eczema and hay fever. They make fewer visits to the doctor and have a reduced risk of leukaemia, cancer and diabetes.

Older siblings prevent younger ones being bullied.

In larger families play is less closely supervised. Children learn to take risks, which will make them better employees and employers.

Children in large families learn to cook, use the washing machine and to iron.

In larger families there is more emphasis on thrift.

Those who grow up with siblings are better at getting on with the opposite sex and have fewer divorces.

Cons

Developers are building so few larger homes that a third bedroom can add a fifth to the price of a house, and a fourth two thirds.

In some countries, the tax and benefits system has left larger families living on average incomes worse off.

Converting a loft or basement could mean higher council tax bills.

Family tickets for many attractions are limited to two children.

Tax on larger cars may soon be followed by dearer parking.

Many swimming pools allow an adult to supervise only two children.

In Australia there are proposals for a carbon tax on parents with more than two children.
