1. Changes in Eating Habits
Every parent knows that a loss of appetite in a child is often a sign of illness. If a child who normally eats well suddenly starts eating less, accompanied by fatigue, discomfort, a feverish forehead, flushed face, and restlessness, they may have a fever. If the child has bloating, persistent vomiting, or foul-smelling gas but isn't feverish, the cause could be an issue with digestion, such as milk stagnation or poor digestion.
Parents should be especially cautious if a child refuses to eat or cries after eating, or if they experience excessive vomiting, as these may indicate a mouth infection or, in some cases, a contagious hepatitis infection.


2. Bowel and Urination
Parents should pay attention to the frequency of bowel movements and urination in their child to determine whether it has significantly increased compared to normal, and whether the consistency is normal.
If a child hasn’t had a bowel movement for more than two days, or if they are having three bowel movements daily, or if the stool is loose and not formed, or if urination is less frequent and turns yellow-red with pain or discomfort during urination, these are signs of abnormal conditions. It is essential for parents to seek medical attention promptly.


3. Changes in Sleep Patterns
Parents should also observe if a child, who previously fell asleep easily and had regular breathing patterns, is now having difficulty falling asleep, tossing and turning restlessly on the bed. If the child used to have a set sleep schedule but now requires constant calling to wake up and then immediately falls back asleep, or seems excessively sleepy, it may indicate early signs of some neurological issues. If the child sweats heavily after sleep, it could be a sign of rickets.
If the child wakes up suddenly in the middle of the night and pulls at their anus, it might suggest the presence of pinworms. If a child sleeps with their mouth open and snores loudly, it is likely that they have nasal congestion, swollen tonsils, or enlarged lymph nodes.


4. Changes in Respiratory Patterns
The respiratory system in young children is still developing and fragile, which makes them more susceptible to unusual breathing patterns when they are ill. If a child's breathing becomes louder, faster, and their face turns red, it may indicate that they have a fever.
If a child starts breathing through their mouth or takes deep breaths, it could be a sign that their nasal passages are blocked or congested. If they experience rapid breathing, have difficulty lying down comfortably, and are also showing signs of fever and coughing, it may suggest a bronchial issue. In cases where the child exhibits rapid breathing, flaring nostrils, and their mouth or lips turn blue, it could be a sign of pneumonia. Parents should closely monitor their child’s breathing patterns.


5. Về thần kinh
Rất dễ có thể nhận ra những trẻ bình thường vì những đứa trẻ khỏe mạnh thường tinh nhanh, hoạt động tinh lực dồi dào, mặt mày rạng rỡ, tươi tắn, hai mắt sáng long lanh. Nếu phát hiện thấy trẻ không thích nói, không thích chơi, nghịch như lúc bình thường, người buồn bã, chân tay rã rời. Đó chính là trẻ đã có bệnh.
Ngoài ra nếu bạn thấy ở trẻ có biểu hiện nôn nóng, cồn cào, bất an, mặt đỏ đậm lên, môi miệng khô táo thì phần nhiều là triệu chứng bị sốt. Nếu ánh mắt đờ đẫn nhìn thẳng, hai mắt trừng trừng, hai tay nắm chặt thì đó là dấu hiệu báo trước sẽ bị kinh quyết. Nếu hai chân co quắp, người quằn quại đó là biểu hiện của đau bụng. Nếu luôn buồn nôn, nôn mửa, ở phần thóp trước của trẻ bị lồi lên, cổ cứng đơ ra. Đó là triệu chứng của viêm màng não.


6. Về sắc mặt
Con bạn bình thường lúc khỏe mạnh thì sắc mặt hồng hào, tươi tắn, hai bên má mịn màng, ở bộ phận nào ở trên mặt cũng đều rạng rỡ tươi sáng.
Tuy nhiên khi có bệnh thì sắc mặt trở nên trắng bệch, xanh xao, vàng héo, xung quanh môi, mũi tím bầm lại hoặc hai bên má có quầng đỏ khác thường. Các bạn hãy theo dõi xem con mình có những biểu hiện khác thường về sắc mặt không nhé. Nếu có hãy cho con đi khám bệnh viện ngay nhé.


7. Regarding Eye Condition
For healthy children, the eyeballs typically appear bright and alert. This is something every parent knows. However, when a child is ill, their eyes can become dull and lose their lively, sharp expression. In severe cases, the eyes may roll back, a condition commonly referred to as "the whites of the eyes showing".
It can be quite alarming to witness. If a child’s eyes become bloodshot, tears flow continuously, they become sensitive to light, or their eyes are sticky with eyelash residue, this indicates an eye condition that requires attention.
