My baby passes a lot of urine..is it normal?

There is nothing to worry about. It's absolutely normal for babies to pass a lot of urine. Some babies pass urine 15-18 times a day (or even more), others pass urine only 8-10 times a day. As babies get older, they urinate fewer times in a day, but tend to pass a lot more urine each time. Don't worry as long as the kid is healthy :)
