How much and what type of drinks should my 14 1/2 month old be drinking through out the day?

He should be drinking about 20 ounces of whole milk per day, 1 cup of juice (so if you water it down it can be two different servings in the day) and as much water as you can get him to drink!

He should be drinking up to 24 ounces a day of milk (one cup per meal), and 8-12 ounces of juice total per day. Milk is good for children, in moderation. Too much juice or milk will lead to the child being overweight and can cause damage to developing teeth. Also, too much juice can give your little one diarrhea. By all means, give him as much water as he wants to drink.

He should be consuming as much as he wants of 100% juice, water or a mix of both. Try to steer away from Juicy Juice it will often give a child the runs. But when it comes time for him to eat stall on giving him any at all so that way he will eat more and drink less. You might want to try Welches 100% juice, they have no red dye of any kind(which promotes hyper activity in children) and they use only fruit sugar to flavor it and dyes from fruit to color it lightly.

Everyone needs to have some plain water each day to help regulate their 'body machine' as it were.

But most fluid intake is determined by thirst and meals that are being served.

If you need specific direction to match your child, call the pediatrician. Not all children hydrate the same way nor are their needs the same.
