If they want to point out potential harmful behaviours, they should do that, and then they would get called out on doing so with little to no evidence. Instead they went with "weird" because they have no argument per se.
Given that as far as I know, room-sharing is not standard Western parenting practice, I believe they have backed up with an appeal to authority the idea that Western style parenting is harmful. Furthermore, link [1] contains a link to [3] which is an recommendation from a pediatric journal that provides links to scientific papers that suggest room-sharing reduces SIDS risk by up to 50%. (see bullet point 4 of link [3]) Thus I think the appeals to authority are backed by evidence.
Thus I think that the article could have made a stronger point if they had talked about room sharing more instead of bed sharing, but I think they do have an evidence backed point that Western parenting is potentially harmful. They avoid ruffling parent's feathers too much by understating their point.

It's great to steelman someone else's arguments in a discussion. It's terrible to let BBC print garbage with clickbait headlines without criticism, because it will keep happening, and its bad for society.
It doesn't make the point your making, and the way it goes about making its point is not something I'd accept in an inclusive society.
