We use phones, iPads etc. as a part of our daily life. As a parent you might want to hold back a bit on that, because it affects language learning in your baby.
Imagine being a little kid and your mommy keeps shifting her attention from you, breaking eye contact and her emotions change without a noticeable reason? To a little child that cannot “hear” or “see” the other party in the mum’s conversation that makes no sense. They do notice that their playtime gets interrupted so their attention resets completely instead.
Such a thing can have a very negative impact on their social and language learning.
I am not a perfect parent myself, I know it’s unavoidable to use your phone for social or business interactions, but for the sake of my child I put aside my phone during playtime and dedicate my time to only the two of us.
