Most of us talk to our little babies in childish language with a pre-conceived notion that this is the language babies understand. But this is not the case; babies will understand what you will teach them. The way you speak bears great influence on a child's mind.So make it a point that you never start talking to your kids in childlike language.

Babies are fast learners and the way you talk to them initially will have effects on the way they speak later.
So make sure you speak to your baby in a way that's clear and grammatically correct. Even a clear language with proper vocabulary can be sweet, polite and good to listen.
