Patient's question:
My child is almost 19 months old. He doesn't focus well, doesn't really like making eye contact with adults, and doesn't pay attention to the pronunciation of words when you talk to him. Now, he only knows how to say "mama," "papa," "bye," and "fly." Everything else comes out incoherently. Occasionally, if you ask him to say "elephant," he can, but he forgets it afterward. He only calls "mama" and "papa" when he feels like it. Children younger than him can already speak, but he still seems to be in the babbling stage. He's very active, will greet others with "ah-ah" on his own, play, and imitate actions quickly (when he's willing), loves watching commercials and singing on TV, and can stay calm for a while. When I teach him to read, he always flips the pages himself. He likes the pictures.Doctor's answer:
Hello! Normal language development is related to many factors, such as genetics, hearing, environmental education, intelligence, etc. These factors are interconnected, so there is a significant individual difference in language development. Most babies can say single words around 9 months old, 2-3 words by the time they are 1 year old, and can say several meaningful words or simple sentences by 1.5 years old. Around 2 years old, they start using pronouns like "I" and "you," and by 3 years old, they can speak fluently. You can engage your baby in simple language games and encourage them to pronounce.Lymph nodes are a part of the human lymphatic system, composed of lymphatic tissue and reticuloendothelial cells, distributed throughout the body's lymphatic system and connected by lymphatic vessels. The lymphatic system in children is not fully developed at birth and undergoes the most vigorous development during the first decade of life, especially in early childhood. Therefore, lymph nodes are generally not palpable in newborns, but healthy infants and young children often have superficial, single, soft or slightly firm, and painless lymph nodes the size of green beans to peanuts in areas such as the neck, submandibular region, behind the head, in front of the ears, and groin. This is a normal physiological phenomenon.
Lymph nodes play a crucial role in protecting children's health. The lymphocytes generated by lymph nodes have immune functions, filtering, clearing, and phagocytizing bacteria within the lymphatic vessels. If there are no other abnormalities in your baby, you do not need to worry too much.
