My Baby (11 months) pees a lot like 3-4 times in an hour. is it normal or should I consult some doctor?

A. A frequent need to urinate. A child's bladder is small and does not hold as much urine as an adult's bladder. For this reason, frequent urination is common and is not necessarily a sign of a urinary problem. Your child may urinate more because he or she is drinking extra fluid, feeling nervous, or simply from habit.
