Introduction:
In the chapter "BIRTH" by A.J. Cronin, Andrew describes a situation where a child is brought to him for treatment. The child's condition is alarming, and Andrew senses that something is seriously wrong with the child. He examines the child carefully and identifies several symptoms that indicate a serious illness.

Physical Symptoms:
Upon examining the child, Andrew notices that the child is pale and weak. The child's pulse is rapid, and the heart rate is irregular. These physical symptoms indicate that the child is suffering from a serious medical condition.

Respiratory Distress:
The child is also experiencing respiratory distress. Andrew observes that the child's breathing is rapid and shallow. This suggests that the child is struggling to breathe properly, which is a significant cause for concern.

Cyanosis:
Another alarming symptom Andrew notices in the child is cyanosis. The child's lips and fingertips have a bluish tinge, indicating a lack of oxygen in the blood. Cyanosis is a critical sign that the child's condition is deteriorating rapidly.

Poor Feeding:
Andrew discovers that the child is not feeding well. The child's mother mentions that the child has been refusing to drink milk and is generally uninterested in food. Poor feeding can be a sign of an underlying illness or discomfort.

Failure to Thrive:
Furthermore, Andrew observes that the child's growth is stunted. The child is significantly underweight for their age, indicating a failure to thrive. This could be due to a chronic illness or a lack of proper nutrition.

Conclusion:
Based on these symptoms, Andrew concludes that the child is suffering from a severe medical condition that requires immediate attention. The child's physical weakness, respiratory distress, cyanosis, poor feeding, and failure to thrive are all indicators of a serious underlying problem. Andrew realizes that urgent medical intervention is necessary to save the child's life and improve their overall health.
