Children's weight should be monitored after age one

Recently, a photographer friend of mine received a lot of attention for a photo she shared of a baby (not the child pictured.) The baby, about six months old, looked similar to the Michelin Man, because he had lots of rolls of cute little baby fat. Most viewers commented on how adorable the baby was, but several expressed concern that the baby was morbidly obese. Eventually, the photo was taken down out of respect for the parents.

Some babies are just chubby, so I don't think it's something to be alarmed about -- and I think that the commenters who were so quick to judge a child they didn't know were just plain rude. And according to this article, fat babies are not a concern to doctors, though a child's weight should be monitored after the age of one.

Would you be quick to point it out if you thought someone's child was obese?
