I'm not in the USA, and I think most parents I know want a separate room for their baby - it's only for economic reasons in most cases if that doesn't happen.

I'm not in the USA, and I think most parents I know want a separate room for their baby - it's only for economic reasons in most cases if that doesn't happen. The only people I know who don't have their baby in a separate room still have an empty room in their house. It was a very strange factoid to put into the article, but because it was at the start I immediately skimmed the rest doubting it's research or authenticity.
