But let's talk about some external reasons. First of all, boys are much more prone to speech delay than females by a landslide. We don't know why. At this moment, it's just a statistic. Second of all, a very prevalent middle ear infection to be more prominent in kids than adults like us. And when they cannot hear a lot of things, that means they don't get 100% of the language modeling you're giving them. And third of all, there might be a family history of literacy problems, speech delay problems, language delay problems. And the fourth thing is parental interaction. You need to upgrade your interaction in order to decrease the risk of your child having a speech delay so it doesn't matter if they have it or don't have it. It's better to always upgrade your interaction so that you get a better quality of communication at home.
