What may the other side argue?

My research question is stated as "When it comes to early childhood development of eating habits, who is more at fault: the naive child, or the influential parent? What affect does this have on our food system?". This question basically opens up the idea that parents do play a huge part in a child's eating habits. In my opinion the parent plays a tremendous role in this part of a child's life. Children are a reflection of their parents in many ways, the parent generally lays out the foundation for the child's eating habits, and I have figured that out along the way.  Throughout this research process I hope to find out the truth on how big of a role the parent really does play in a child's food life. I also hope to gain many different standpoints on this topic, not reading and bias opinions. This way I could have my own outlook on the issue. Hopefully with the information i gain, I find out how this all connects to our food system. If we find the root to the problem, we can ultimately eliminate it. The only trouble I'm having this stage is understanding the other side of the argument and how some people may argue that parents don't affect their own children's eating habits. This is something I would like to implement into my essay. My purpose for the essay isn't just to throw my opinions onto the reader, but to also add facts and the other point of views from other people into their minds. I ask if anyone may know what other opinions the article may show, or any other opinions you may have in particular, please do share.
