*One mother tells of how continuing to nurse her son has helped control his behavioural problems.
Vickie Krevatin's four-year-old son, Jessy, was recently at a party that left him uncontrollable with excitement. When Vickie's attempts to stop him knocking over drinks, shouting and throwing toys failed, she took him to a quiet room and let him suckle her breast.
Jessy is 3ft 3in tall and old enough to start school next month, but Vickie breastfeeds him five times a day because, she says, it alleviates his symptoms of attention deficit hyperactivity disorder (ADHD).
"Every time he is offered 'boobies', he is calm," she says. "Breastfeeding is as effective as drugs for keeping his symptoms under control."
Despite the well-known health benefits of breastfeeding, only one per cent of British women do so exclusively for the World Health Organisation's recommended six months, while extended breastfeeding is so rare it is seen as a taboo. Last month, US mother Jessica Anne Colletti, 26, caused controversy when she posted a picture online of herself breastfeeding her 16-month-old son and his 18-month-old friend.
"I know people don't regard it as normal, but I don't care," says Vickie, 42, from Basingstoke, Hampshire.
ADHD's main symptoms are hyperactivity and impulsive behaviour, thought to be caused by underactivity of chemical neurotransmitters in the brain. Diagnoses have soared in recent years - the NHS estimates that between two and five per cent of school-age children suffer to some extent, although some experts believe the rise is due to other health complaints or a child's natural exuberance being misdiagnosed.
While there is no cure, the most common treatment is methylphenidate, a stimulant commonly known by the brand name Ritalin, which increases the activity of the neurotransmitters dopamine and noradrenaline. Figures last month showed that prescriptions for Ritalin have more than doubled in a decade, reaching almost one million last year.
Jessy, diagnosed with ADHD in February, has been taking Equasym XL, another brand of methylphenidate, since March, but Vickie maintains breastfeeding is essential in helping to calm him. There is no research to support her claim, although breast milk does contain naturally occurring chemicals that induce sleepiness.
Research also shows that nursing may protect against ADHD developing in the first place. In June 2013, a study by Tel Aviv University found that children who were bottle-fed at three months of age were three times more likely to have ADHD than those breastfed during the same period, but it is not known whether this was due to the breast milk or the bond formed between mother and baby.
Being breastfed since birth, however, did not prevent difficulties with Jessy. "As a baby he wouldn't sit still for longer than 15 minutes. If I put him in a car or buggy, he would scream," says Vickie, who quit her job as a financial crime auditor when Jessy was six months old and now works from home as a jeweller. "As he got older, he was so destructive we would be reduced to tears."
The only thing that calmed him was being close to his mother, and for the first six months Vickie breastfed him up to 18 times a day.
