Did Western Society Create the Difficulty of Sleep Training?

I know there has and probably always will be an argument over things like co-sleeping in the realm of parenting. I’m not here to take sides, but to offer up an interesting article that I found. The article titled, “Sleep Training: It’s a First World Problem”, made a couple of good points that I thought were worth sharing. The post talks about how co-sleeping is a normal thing in many societies where families live in smaller houses or even huts. It also draws evidence from history of co-sleeping in families. The article is pretty one sided in support of co-sleeping, but to be fair I gave you a heads up. If this is something that interests you then go ahead and check it out!
