Children shun fictional 'fat Alfie'
Many children said fat friends was less likely to be invited to parties and was more likely to be naughty than thinner characters. This means that our society is so conscious of body shape that even young children are able to mirror back what we say about obesity because children like this are a social barometer.
It is very important that we help children not to get bad perspective. We should teach our kids how to treat other people. To do that, we set an example to our kids. Once we don't judge by appearance, our kids take their cue from us.
