One of the most common first words for babies to say when they're learning to talk is "mama", and while many parents hope that their child will also learn to say "dada" just as quickly, language experts have claimed that's unlikely to be the case.
Instead, researchers believe that babies often have the exact same first words regardless of what language they speak, and have claimed that those words include "this" and "that".
According to a research team from Cornell University in the US, the earliness with which children begin to use "this" and "that" - which appear in many kids' vocabulary between 12 and 18 months - shows that they are eager to share attention, and that focusing on the words is also a result of children finding it tough to understand others' perspectives.
