New Illness. Coming down with an illness is the main physical cause. Young children cry about being sick, even if they don’t have any pain.
Physical Pain. Painful causes include earache, sore throat, mouth ulcers, or a raw diaper rash. A sore on the penis or constipation may also cause pain or crying.
Behavioral Causes. Most crying means the child is upset about something. Crying can occur when a young child is separated from his parents. Other examples are crying with tantrums or when overtired. This guide detects many babies with sleep problems. Crying always occurs during re-training programs for bad sleep habits. Some preverbal children cry any time they want something.
Hunger. After the early months, most parents can recognize hunger and feed their child. If they don’t, the child may cry.
Cold Medicines. Drugs like Sudafed can also cause crying. Note: FDA does not advise cough and cold medicines for children under 6 years.
