Ants Attracted To Child's Urine, Wet Pants. No Signs Of Diabetes. Reason?

For the last two to three months, we have observed that ants are attracted to our 18 month old son's urine and wet pants. He usually urinates at 30 minute intervals after consuming liquids. He is exhibiting no other symptoms of diabetes, like weight loss or excessive hunger, thirst, fatigue, etc. I am very worried as my father-in-law is diabetic, although no other relatives are. Does the above symptom alone give reason to suspect my child has diabetes
