Kate Gosselin has been a controversial mother and many people feel she exploited her children. However, she has always attracted attention and having a special needs child is something that many other parents can relate to. He going public shines a light on the struggles faced by every family with special needs children.
When is comes to raising awareness of the problems of special needs children, the more people talk about it the better. When famous people do this it raises awareness even more, which might compel people to be more understanding and in some cases might even compel them to contribute money to help groups that help children.
Collin Gosselin, who is one of Kate Gosselin's sextuplets, is a child who has special needs. The family has chosen to keep this matter private, although by going public they could be raising awareness for the child's particular struggle. However, this being stated, publicity can be like a two-edged sword to where the public could accuse the Gosselin family of exploiting their child in order to maintain fame or receive monetary gain.
I do not believe for a second that Kate is going public about Collin's special needs to raise awareness. In fact, she doesn't give any details about what he is suffering with in her latest interview. Instead, she is choosing to sell her son's and her family's privacy just to make some more money and stay in the spotlight.
