I have several simple methods, which I summed up myself, hoping to help.
1. Don't know your baby too well at ordinary times. Don't let the baby know what he wants by pointing. Encourage the baby to say it. For example, if the baby wants to drink water, don't take it in a hurry. Ask him repeatedly what he wants. If he doesn't say anything, you will ask, "Do you want some water?" Until the baby says it, even if it is a favor, of course, it is best for him to say "drink water."
2. Talk to your baby more. Even if the baby doesn't talk, you should talk to the baby more often, and always ask what's wrong with the baby, so that the baby can have a chance to talk to you.
3. Pay attention to the words that the baby usually likes to recite, and then whenever the baby says those words, you follow the baby, and then the baby forgets whether you are teaching him or he is teaching you, and then you suddenly become other words. Remember to start saying simple overlapping words, don't say awkward words, don't say children's words.
4. You can play a toy with sound for your baby, or an early education machine with a card. As soon as the baby presses it, simple words will appear, sometimes very interesting, and the baby will continue to learn by himself. Now I'm still young, so I don't have to care too much about letting my baby know what's on the card, as long as he is willing to say it, but it's not difficult for my baby to recite a card skillfully every day.
5. Sing a song or bedtime story to your baby, slowly. Sometimes the baby will say a word or two when he hears some words. You can also download bedtime stories to your mobile phone or P4 and play them to your baby at ordinary times, which is also helpful.
