Alright, so what we're going to do here is put all of these language development milestones in order and for the milestone listed with an asterisk, we're going to write the approximate age when that would happen on our timeline here. Alright, so we have birth and then our first language milestone is going to be cooing, right? The emergence of those vowel sounds: ahs and oohs. So, we're going to put cooing there, and then after cooing, once we've kind of got those vowel sounds mastered, we're going to begin combining consonants and vowels in babbling. Right?
We're going to put babbling next or "baz", "mad", "dav", "gaz," all that good stuff. After that, usually, we're going to have the emergence of first words. So first words are usually going to happen around 12 months of age, give or take. Right? And that range is typically going to be between, like, 10 to 18 months usually.
So, we'll have our first words happening somewhere around the first year of life. And then after that, we're going to see those very shortened sentences. So once we've kind of mastered a couple of words, we're going to begin combining words to make short sentences or telegraphic speech. So, our telegraphic speech happening usually around age 2, and then from there, sentences will continue to get longer until eventually, children begin to make those overregularization errors around age 4. Right?
So we see that overregularization, where they're basically applying regular grammatical rules to irregular verbs and nouns, and then usually that will disappear by about age 5 or so, and then by about 5 years of age or 60 months, we usually have those adult-like grammar skills by then. Alright. So there you have it, and I will see you guys in our next one. Bye-bye.
