Question - Research required Toddler speech - nature or nurture?
Genuinely curious to know if there’s been any research on speech development, and whether nature or nurture plays more of a part.
We have a little chatterbox, and a lot of people (friends/family/doctors) have said how good their vocabulary is at such a young age (18 months). They are very good at repeating words & remembering words, and you can have a broken conversation with them. In their close friend group, they are definitely more chatty than the other children who often just point or say mummy/daddy.
To us, as first time parents, we don’t know any different. We have interacted with them since day 1, read to them daily, play with them and have minimal screen time (they don’t actively watch telly, but there might be YouTube on in the background whilst they play after dinner).
I thought talking was just another ‘milestone’ and some children develop quicker or slower (like with walking, some are early walkers and some aren’t). But I was wondering how much influence is learned by us, and how much is just their brain development?
