If you really do want to go into the rabbit hole, you have to understand the therapy for apraxia speech is different from if your child only had a speech delay is different because then we have to think about things that they have a problem with. Number one is that they cannot do more syllables. Whether it's in a word or in a sentence, the harder it is to say it correctly. Number two, the flexibility of using those sounds are also toned down. Right. If you see that your child have very few consonants, the syllabic structures are very reduced, made simple. Right. They're babbling. They don't do a lot of reduplicating stuff like, like an ambulance, then maybe there might be a case. But most of the time, statistically speaking, it's quite unlikely that your child has apraxia of speech.
