Usually, babies will call mommy and daddy when they are 12 months old, and their pronunciation may not be very clear at that time. However, as the baby grows older, the language center develops gradually, and usually around 14 months of age, the baby can call out mommy and daddy clearly. The baby’s language development is related to the normal development of the brain, hearing and throat muscles, which need to go through three stages: vocalization, understanding and expression. So create a good language environment for your baby, communicate with your baby often and encourage your baby to learn to speak. You can teach your baby to say some simple words that help language development, and your baby may call mommy and daddy earlier. Generally, by 18 months of age, babies will not only call mom and dad, but also be able to identify and say the names of the main members of the family. If your baby is still unable to speak or name family members, it is recommended that you take your baby to the hospital for relevant examinations, such as brain development, vocal cord development and auditory development, to find out the cause of your baby’s delayed language development and to intervene as soon as possible.
