What should I do?
Babies of this age love to be stimulated by vocal play and interactions. Your baby will be delighted when you invite him to whisper. She will be able to imitate vowels and then say simple words with the help of vocals that your baby can master. You can make a conversation with him so that it gives him the opportunity to talk then you answer or vice versa. Respond enthusiastically so that your baby responds to do the next vocal. Introduce your baby with simple words that are applied in everyday life. Use adult words, expert research suggests that babies can understand long words before they are able to pronounce them, and habits
good speech helps shape the baby’s speech patterns. When you talk to your baby, slow down your speech and emphasize single words then you can point out the object in question to add more interest in communicating with you.
Then give the baby the opportunity to respond. You can read story books because babies will love being read from books with large, brightly colored pictures. Apart from helping him form good speech habits, the baby will sharpen his sight with these images. Do not force your baby to communicate too much, as adults babies have a mood when talking. Sometimes babies are not in the mood for a voice. If your baby turns away, closes his eyes, or gets fussy, just let it be common, your baby is needing time to rest. At this age of 4-7 months, babies have developed communication, including being able to recognize and respond to their names, then they can make sounds with various vowels so that the baby begins to respond and imitate the expressions of the other person. If at this age your baby has not shown good communication and is not sensitive to the response given by you without having a facial expression, you should consult a doctor to find out what problems your baby has.
