UTIs inflame the bladder and cause discomfort leading frequent urination, says WebMD. UTIs may have other symptoms such as painful urination, fever, bloody or cloudy urine, back pain, and nausea. Urinalysis and urine culture tests are important in evaluating UTIs in infants, notes About.com. Frequent daytime urination syndrome is common among children aged between 3 and 8 years. It occurs during waking hours and is believed to be stress related. Infants with the condition urinate between 10 and 30 times a day. The syndrome usually disappears after two to three weeks without the need for treatment, explains WebMD.

Children with diabetes urinate frequently and with large amounts of urine per urination. They may also have other symptoms such as polydipsia and weight loss. In diabetes insipidus, the kidneys are unable to conserve water, leading to excess urine and a thirsty feeling. Inflammation of the meatus in boys and inflammation of the vaginal area in young girls may also cause frequent urination, states About.com. Caffeine consumption increases urine output and may cause bladder muscle spasms, says WebMD.
