The amount of fluid a child needs depends on many factors including their age, their gender, the weather and how much physical activity they do, but generally they should aim to drink about 6-8 glasses of fluid per day (on top of the water provided by food in their diet).
Babies of this age are able to hold objects and can learn drinking liquids from a cup. Give your baby a sippy cup that does not have a valve, so he can suck easily. Choose one which can hold 4-6 ounces of liquid, and fill it up to the top so your baby does not need to tilt his head up when sipping. A large cup filled with water may be too heavy for a small baby to use.
