Believe it or not, the process of turning language into speech is actually a pretty complex thing to do. Our brain, lips, tongue, and mouth all do a sophisticated dance every time we talk.
So it’s no surprise that when children are learning to speak, they’ll sometimes mispronounce words. It can be hard for little lips and mouths to make complex sounds!
But while common word fumbles like saying ‘tat’ instead of ‘cat’ may be normal at a certain age, sometimes talking troubles can be a sign of a more significant speech disorder.
