What is the normal urine volume for a nine-month-old baby?

For new parents, there are many things they don’t understand, so there is a lot to learn in the process of taking care of the baby. Especially in some details, if you don't pay attention, it may affect the baby's health. For example, the baby’s urine volume problem. So, what is the normal urine volume for a nine-month-old baby? In fact, there is no specific judgment standard, and it is related to the number of times the baby drinks water.

Less urine but more frequent

Because the baby's development is not yet mature, it is easy to be affected by the external environment, suggestive language, etc., and its control, stress resistance and expression ability are relatively poor. Therefore, any slight stimulation, including the stimulation of residual urine on the foreskin and genitals, the friction of uncomfortable clothes, the sound of gurgling water, whistle, etc., will make the baby feel the urge to urinate.

Under normal circumstances, babies urinate 8 to 15 times a day and night. If the frequency of urination increases significantly and exceeds the above range, but the total amount of urine does not increase and the amount of urine each time is still very small, then the mother should pay attention to the baby's other reactions.

Frequent but small amounts of urine are usually a warning sign for the following diseases:

1. Neurogenic urinary frequency refers to the baby's bladder detrusor underdevelopment and incomplete nerves. Daytime spot polyuria may occur, up to 20 to 30 times, but normal urination at night, with a tendency to recur, and urine tests are normal.

2. Inflammatory stimulation can lower the nerve perception threshold, and the urinary center is in an excited state, resulting in frequent urination and reduced urine volume. Therefore, cystitis, prostatitis, urethritis, pyelonephritis, chronic balanoposthitis, vulvitis, etc. can all cause frequent urination, often accompanied by symptoms such as urgency and pain when urinating. If the baby cannot tell, he will often cry when urinating.

3. Non-inflammatory stimuli, such as urinary stones, foreign bodies, etc., can also cause frequent urination.
