In reading the other responses, I would be cautious about giving juice. Infants given juice before the age of one are at a much higher risk for developing diabetes later in life. So be cautious, and if you do give juice, give just a little. Could you call your kid's pediatrician, and ask him or her what they think about it? Our pediatrician recommends the following: 1. Adding 2-3 ounces water daily, 2. Changing formula brands. They recommend Good Start formula to help with this issue. 3. Add corn syrup to a bottle. Start with a low dose (1-2 tsp per day), and increase by one teaspoon increments per day to a max of 1-2 tsp per bottle for 6 bottles per day. Do not use honey. The goal is to produce a soft bowel movement at least daily. 4. If corn syrup fails after 4-5 days of use, discontinue and try a fiber source such as Maltsupex. The dose is 1/2 to 2 tsp, 2-3 times daily. This is an OTC, but it has to be special ordered by the pharmacist. 5. If all else fails, consult your doc for instructions for infant sized glycerin suppository use. 6. Lower abdominal massage may help.
Good luck. Hope that helps.
