The Main Claim of this article is straightforward. The Claim is that Childhood sleep issues have the potential to raise the risk of suicide for said child in the future. The News source is CNN. CNN has been known to be partisan towards Democrats and democratic beliefs. That being said, outside of its partisanship, it is known to be a fairly reliable news sight. The article's writer is Kristen Rogers, a legitimate writer who has written many articles for CNN in the past.
This article is from a couple of months ago, but is still relevantly new. It is still pretty current and up-to-date. There are also many other articles covering the same study as this one, such as this article from WAGM 8. Reading through the article, most of the quotes seem on par with what you would expect to hear, and nothing jumps out as being untrustworthy.
The article doesn't seem to be biased in any way, and the claim(s) that are being made in the article directly connect to the main claim in the title.
This article, in my opinion, seems to be based on very reliable data from a study written by PhD receivers who know what they are talking about. This article is not on a political topic, and because of this, I think it is very easy to trust this article written by CNN as it has sources to back up the claims it is making and directly lies on what seems to be a reliable study.
