Pronunciation changes are a pathological symptom of dysphonia, mainly manifested as delayed and abnormal pronunciation, the development speed of pronunciation is lower than the corresponding age, and the speech is slurred or mispronounced. The most easily mispronounced sounds are s, z, c, sh, ch, zh, l, m, n, j, x and so on. So how to avoid the child’s pronunciation change in the diet? 1.For babies born in full term and healthy, they need to introduce supplementary food in time after 6 months. Due to the individual difference of child development, the time of introducing complementary food should not be earlier than 4 months, but not later than 8 months, which is the “window period” for training baby to chew, swallow and oral coordination. 2, after adding complementary foods, you need to constantly change the baby’s eating pattern, from thin to thick, from soft to hard. Such as full 4 months of age to add liquid-like food, full 6 months of age need to try pureed food, such as baby rice flour puree, meat puree, fish puree, vegetable puree, fruit puree; 7 to 9 months of age can gradually transition to the end of food, such as thick porridge, rotten noodles, minced meat, minced vegetables, fruit pieces, etc., 10 to 12 months of age can gradually transition to the end of food, such as broken buns, soft rice, minced meat, wontons, fruit strips, etc.. After the age of 1 year can gradually transition to the adult diet mode. 3, after the addition of complementary foods for infants, parents can not always feed the child, but also need to gradually train the child’s ability to eat on their own, even if they eat a “mess”, which is conducive to training the child’s coordination and ability to eat on their own. Some parents like to feed their children, even to feed their children in elementary school, this practice is obviously inappropriate, seemingly “love” children, but actually “harm” children.
