Bad Parents Feeding Their Children Junk Food

I see parents feeding their children maccas almost daily. I know someone that does this and her children are getting out of shape and they are still little. Every time I see her she has some sort of milk shake etc and she is has got very large in the past 6 months. I feel for the children because that has become their normal. I can’t say anything because I would probably make enemies with a few people at work.
