Babies will shiver when they pee or when they want to pee, called urinary tremors. If your baby shivers, observe if he or she has peed and wet his or her clothes, if so it is a normal phenomenon. If your baby is deficient in calcium, it is abnormal to have a urine shiver. Babies in early childhood, because of rapid growth, easily lead to calcium deficiency, so more than 6 months of age, the baby should be timely calcium supplementation, otherwise there will be urine pumping phenomenon. If occasional urination chills occur, it is normal. If the baby eats and sleeps normally and has no other reactions, the baby should be normal.
