Frequent urination in a 7-month-old baby, especially more than 20 times a day, can be within the normal range if the baby is otherwise healthy, active, gaining weight appropriately, and has no signs of discomfort or dehydration. Breastfed babies often pass urine more frequently due to good hydration.
However, it is important to observe:
Whether the urine is clear and not foul-smelling
If the baby has any fever, vomiting, irritability, or poor weight gain
Any signs of excessive thirst or poor feeding
You are giving breast milk 5–6 times a day and some solids with a small amount of water, which is fine for this age. Rainy or cool weather can sometimes reduce sweating and increase urine output too.
Since you had gestational
diabetes, it is good to be cautious. There’s a very small chance of increased urine frequency being related to underlying issues like infantile diabetes or a urinary tract infection (UTI), though these are rare.
Next Steps
Monitor for any other symptoms as listed above.
Get a urine routine examination done to rule out infection.
Visit your pediatrician if the frequency continues to be unusually high or you notice any other concerns.
