Brief Answer:
This is mild hypothermia and rewarming is the treatment

Detailed Answer:
Hello

The temperature between 90 to 95 F is mild hypothermia. The infants are more prone to hypothermia due to immaturity of the thermoregulatory system.
The common causes of hypothermia are exposure to cold environment and overdosing of antipyratic. Some uncommon causes are thyroid hormone deficiency and consumption of few medicines.

The symptoms may be mild to severe depending on the patient's individual response and degree of hypothermia.The first symptom of hypothermia in infant is shivering(to increase the heat production).There may be shallow breathing,decreased activity,poor cry,nausea vomiting or slow pulse.
As he is suffering from croup, I would like to know whether you have given him extra dose of paracetamol(antipyratic)

If there is only shivering and there are no other symptoms.You can try rewarming at home,by shifting the baby to warmer area,proper clothing(most of the heat loss is from head,so head covering is must) and putting blanket to cover the body.Meticulous monitoring of temperature is must.

If there is progressive fall in temperature or there are other symptoms with decreased activity I would suggest you to consult your physician immediately.

I would be glad to answer if there is any further query.
Wish your son good health.
