Many parents worry when their newborns are slow to gain weight. So how long does it take for them to catch up with their peers?
A new study encourages parents to be patient and not worry, because it may take as long as the 10 years. The study is published in "Pediatrics", after British researchers followed more than 11 thousand children born in the 90's. Roughly half of the babies who were slow to gain weight during their first 8 weeks caught up by the age of two. But the other half remained underweight throughout their childhood years, but then had a growth spurt during puberty, and finally caught up with their peers by age 13.
Experts say they hope this will encourage parents not to overfeed babies to help them grow, that could instead trigger obesity.
