There is pleasant news for parents whose babies fail to gain weight quickly.

In a large UK study it has been proved that infants, who are slow in gaining weight during the initial months of their lives, generally speed up at the age of 13. They tend to eat a nutritious diet by then and thus put on weight quickly.

Considering this, doctors have warned such parents not to force their slow-growing babies take a calorie-rich diet as this could increase the risk of obesity in them.

But then this doesn't mean to sit back and relax. Parents should keep monitoring their weight and keep in touch with the paediatric.

In 1990, this study was carried out in Bristol. After analyzing the records of about 11,499 children, the study showed that there were around 507 infants who did not gained weight in the first eight weeks of life but then by the age of two years, they recovered fairly quickly.

In addition, there was another group of 480 children who gained a very little weight between eight weeks and nine months but then they started recovering at the age of seven. By the time, they turned 13 they were found at a quick recovery stage.

Both the groups had different patterns of recovery, because there were two different reasons for their slow weight gain.
