My baby is 7 months old and she goes 4 times pee a day . Is it a normal thing or do I need to take any actions on that

Babies are very different in how often they pee. Generally, babies wet 6-8 diapers per day when they are really young and urination gets less frequent as they start taking solids and as their bladder develop more and more. When your baby pees, is the urine a dark yellow? If it is, it could be a sign of dehydration.
