hii my baby is 6 month old and urinating more than 15 times a day but while sleeping he hardly urinates is it normal?

A. A lot of kids are natural bladder control which is why they do not pass a urine when they are sleeping but when they are awake they pass using properly and 15 times is normal that means your child is very well hydrated and if the child show no sign of discomfort then there is no problem at all
