The research has been strong for a LONG time now, so much so, I’m not even sure why researchers continue to need to prove it. Talking and reading to babies from day one (maybe even conception!) will boost their vocabulary and communication skills and most likely improve the parent child relationship.
As babies grow in your language filled family, they get their needs met. They are less frustrated. Therefore, there are more positive interactions with your little one and less negative. Imagine a clearer form of communicating, imagine less tantrums, imagine being able to express feelings to each other, imagine a life of respect and trust in listening to what you each have to say.
It all starts with your newborn.
