Do give this article a read.

I do agree with the piece strongly. I believe that children pick up their eating patterns, mostly out of observation and from learning. In most of the cases, they simply eat whatever is given to them without knowing about the nutritional value. The link between parental negligence and child obesity is clearly drawn here.
I hope that people look into this and give more attention to not just children's behaviour, but also what they eat.
