What is the reason for the baby's urine changing from yellow to white?

Patient's question:

10 days
Detailed medical condition and consultation purpose: The urine appears yellow, but it seems to turn slightly white after a while, a light white. It's a bit thick, much lighter in color than rice water. I had a fever the night before yesterday, but it went down again after a short while. Currently, I'm breastfeeding, and not eating much complementary food like rice or porridge. What could be the reason? Thank you

Doctor's answer:

Hello, dear, this situation is mostly related to drinking too little water. Feed them more water appropriately to promote excretion. If it doesn't improve, you should go to the hospital for a urinalysis to rule out other abnormalities.
The child is troubled by neonatal diseases, so parents must take them to the hospital immediately for treatment to avoid various misunderstandings. It's important to treat them according to their symptoms in a timely manner. For parents, it's crucial to pay attention to the child's condition and do their best to help them get timely treatment for the illness.
