Red urine mostly occurs 2-5 days after birth in newborns, due to less urine and the increased excretion of red urates in the urine due to more decomposition of white blood cells, thus appearing red and may also be slightly cloudy.
Parents need not worry too much, the phenomenon will gradually disappear with the baby’s behaviour such as drinking water, but they should also be vigilant and react more to the doctor and caregivers about the baby’s physical condition to avoid the baby suffering from urinary or systemic diseases.
