Wouldn't you prefer to realize you need something, and then you actively go and get it? I don't want to be manipulated into thinking I need something subconsciously just because I've seen it a bunch of times.
It depends. Sometimes you don't know that a solution exists for your problem.
I think it would be more healthy for your kid if you talked to other parents (and not just for finding solutions to problems).
It is a huge conflict of interest "learning" of a solution to a problem from an ad who's express purpose is to get you to buy it. I agree with the sibling comment; fixing problems is fine but do it from something trustworthy, not the company with the biggest advertising pocketbook.
