Concerned about my 7 year old son...

1ST OF ALL I WOULD CHECK TO SEE IF HE HAS DIABETES BECAUSE IT IS UNCOMMON THAT KIDS WHO HAVE BEEN POTTY TRAINED FOR QUITE SOME TIME AT NIGHT PEE IN THEIR PANTS. DIABETES IS ONE OF THE DIAGNOSIS THAT WE COMMONLY SEE WHEN KIDS START TO PEE THE BED AT NIGHT. THAT DOESN'T REALLY EXPLAIN THE IRRITATION WITH TAGS, BUT MANY KIDS FORM THOSE KINDS OF COMPLAINTS STARTING ANY TIME IN LIFE. HAS HE STARTED TO DRINK AND EAT A LOT TOO? DOES HE HAVE SUNKEN EYES OR DARK CIRCLES AROUND HIS EYES AND FRUITY SMELLING BREATH, I HOPE YOUR PHYSICIAN HAS ASKED THESE KIND OF QUESTIONS. RULE OUT THE MEDICAL STUFF AND THEN THINK ABOUT ANXIETY AND SEEING A THERAPIST.

Are there any other big changes going on in your son's life right now? Starting school alone, can be quite anxiety provoking in kids...So I don't know if I would totally dismiss the issue just yet, especially if school or something else may be bothering him. Kids can totally throw you for a loop with new and different behaviors when something is bothering them. I would suggest talking it out with him...ask lots of open ended questions about school, friends, etc...See what he says or doesn't say...watch his body language. Maybe have him try to jot his feelings down in a journal if he's not comfortable talking. Maybe try having him talk with his dad, aunt, grandma, etc...

As far as the sensitivities, have you tried altering his clothing for a better fit, like buying tagless shirts, etc...? Has this always been an issue..even when he was little or is this something new?

since I have a boy 1yr older it may just be boy 'stuff'. make sure it's pee and not semen. when boys start realizing the penis sticks up sometimes they are having wet dreams. maybe it's because the sensation is overwhelming and in his sleep he also looses his control of urine. my son tried to pee several times when his was hard and went all over his shirt. he cried at first and wanted to know why it wasn't soft. it's normal for him to handle it even a lot at any age. don't make him feel self-conscious but ask if he likes it and if it just started. has anyone at school said if theirs does the same. then you'll know he is talking about it with someone. a man is usually better at it, they make it seem normal and every guy has one and every guy does it. my son eventually grew out of it, but we told him not to touch his unless he was in the bathroom or his own room and NEVER let anyone else touch it. don't freak yet. he is still learning to be a person. my 6yr daughter will take her shoes off if the strings aren't on the sides. if it touches her legs she goes bonkers.

Try putting powder in his pants. Front and back. If he's sensitive, use cornstarch. As far as the other things that bother him... I have a friend who has a daughter who is sensitive to the same things. The tongue in her shoes, the tags on her clothes, etc...
She is just a real drama queen though.
I have heard that the penis actually gets engorged when the body is totally relaxed not necessarily when the male is "excited". So, maybe he's actually a pretty relaxed kid!
Does he share a sibling who is getiing more attention? they tend to over react to not being the center of attention. Is there a new baby? My daughter started peeing her bed when she was seven also, she's 12 now and doesn't do it anymore. She just had a really small bladder and had to grow into it. Sometimes they sleep to heavy and don't wake up enough to feel the bladder contracting, (aka.. the urge to pee).
I have heard alot about little boys in the same age group who start to notice their "penis's" sticking up. I don't think there is much to it though. It seems normal. just don't laugh at him or react at all. Sometimes it is the reaction they crave more than anything.

My son will be seven and started peeing last fall a few times. I was very concerned as you are. I was trying to think is something going on that I am missing. However I was very angry also-so I made hime take his own wet sheets off the bed and put them in the washer and scrub the plastic on his mattress. He also had to go wash himself after every time. That was terrible enough for him. I told him this was his job/responsibility if he was going to keep peeing. He stopped. Next however was going to be to just sleep on the plastic. I know it may seem cruel, but if you can't think that it's anything else but just acting out for no reason.

I am a nurse also-and though I am not a pediatric nurse I have often heard that some children do have this sensitivity it can be real. Before going to a therapist-which I am sure you are at your wits end-it can be a real concern. Often tags need to be cut out of there clothes. Buy the underwear/undershirts that are tagless-I believe it is hanes brand. Don't acknowledge EVERYTHING specifically he says. If he doesn't like the tongue in his shoe-say "I know you don't" calmly and move on. If he says it again, you say it again.
If haircuts makes him itchy,say "It does everyone, and then we can shower and wash it off". I hope I don't sound to cruel-
I have a almost 4yr. old drama gueen at my house and she was like a light switch turning on at age 18 months-let the games and moods begin begin. So different than my son.

Good Luck.
