It is normal for 2-year-olds to talk to themselves. Generally speaking, babies talking to themselves before the age of 3 is a manifestation of language learning and a normal manifestation of the baby’s cognitive development process. 2-3 years old is a critical period for children’s verbal language learning, and it is easy for them to learn and organize the language they hear, and then express it in their own way, so 2-3 year olds often talk to themselves while playing, which is a very normal phenomenon. Parents who find their 2-year-old child talking to himself, do not feel alarmed, you can try to use more of the baby’s mind to communicate with him, you can also guide the baby to play with their peers to communicate, which will help the baby’s cognitive and language learning.
