A new study has some reassuring results for parents of babies who fail to put on weight quickly.

The study found that babies who are slow to gain weight in the first months of their lives generally catch up to their peers later on.

British researchers analyzed data from more than 11,000 children.

Some of the kids who were slow to gain weight in the first eight weeks of life recovered fairly quickly and had almost caught up by the age of 2.

Others continued to put on weight slowly until they were 7 years old, then had a growth spurt and caught up to their peers by the age of 13.
