Confused - medical or behavior Issue? Excessive crying

My 3 1/2 years old boy is starting to worry me.  He constantly asks for something to drink.  Urinates frequently.  We're trying to get him to sleep through the night so we are stopping his liquid intake 1hr before sleep time.  He freaks out over candy and cake.  Very passionate about his sugar. He is extremely picky.  Last Friday, cake was served at pre-school and he didn't get the piece he wanted (not enough frosting) and cried excessively for 30min (2min into the crying, ended up in the car returning home without any cake).  But the part that worries me most is when he takes late afternoon naps (after 3pm), I can count on him to wake up crying for the next 30min.  He is inconsolable.  It's like he doesn't see me and I can tell he's still sleepy.  After he drinks juice or eats a meal, he calms down wonderfully and is in excellent mood afterward.  I list all these because I'm worried about juvenile diabetes but wondering if I'm being overly sensitive.  He's decently active (husband and I are both hyperactive so having an active child seems normal to us), but wondering if excessive crying after nap is just because he's had sensory overload?

You can always check his sugar levels, either by a tester at like walmart or go to the ped and get a test done.  It's just a quick prink and he shouldn't feel much but just make sure you read up on how long after a meal to test him because once you do it he might fight more the second time.  Good luck.

Kaz - crying after a nap is not normal,  but you're describing a child who isn't awake when he's doing this - sounds like a sleep disorder associated with "night terrors" - except his occur during the daytime.  If he's crying and he doesn't "see you" - it doesn't sound like he's awake.  

Does he have trouble with food textures?  Sometimes kids with sensory defensiveness have difficulty coordinating chewing and swallowing,  so they want to drink all their calories - milk and juice.  So they go to the bathroom all the time,  because they're drinking their calories.    If your son isn't drinking water,  but liquids with calories,  it seems like this may be the case.

Best wishes.

It does sound like possible juvenile diabetes. I would definately make an appt with his pediatrician right away to rule it out. 3 1/2 sounds a bit old to be crying like that after a nap. The cake incident could be just behavioral. If he is a picky eater he could be getting too hungry between meals. This could cause bad behavior. If it is JD, you want to treat it right away to prevent permanent damage to his eyes or organs. If it's not, then at least you've ruled out the worst.

I've read that frequent urination and thirst are the signs of juvenile diabetes.  Please test him for that and I hope everything turns out all right.  Keep us posted about your precious one.
