Don’t let a telephone in the hands of a toddler
It’s true, we left the most difficult advice at the end. Yes, it’s highly efficient to show your little toddler a funny video on youtube in order to make him stop crying. But in the same, it’s not recommended to expose a baby to any types of media before 2-3 years old.
Anything we present to a toddler at this young age can have a huge impact on his/hers development, so better be careful than sorry. So no matter how harder it might get, try not exposing the little child to the telephone(except, maybe, for video calls) before the age of 3 years old.
