Response to DH cont'd "So, it appears that you are an idiot and are trying to put your failed parenting on DD instead on your shoulders and on your 13yo where the failures are present.
 

Lather, rince, repeat.

I mean... this IS abnormal and could be a medical concern? Seriously? Why isn't the doctor informed of this issue?

When SS started wetting the bed years past the time when he had stopped, we put him in a diaper. After we had him examined by his Doc.  He was mortified and fixed the problem quikly.  Accountability with a bit of humiliation thrown in works wonders on this type of thing.

At least that is what we found to be the case.

Yes it can be a medical concern and your SS's pediatrician should be consulted. Constipation issues can cause bedwetting in older children along with a variety of other reasons.

ALSO

"Having a smaller-than-normal bladder may make some children more prone to wet the bed. Too little antidiuretic hormone (ADH). Levels of antidiuretic hormone (ADH), a brain chemical that signals the kidneys to release less water, normally rise at night. Some children who wet their beds may not produce more ADH at night."

Hmm well it can and does happen.  I had a child who wet the bed well into their teens, they were extremely embarrassed about it and we did everything we could to help mitigate making them feel ashamed of something they couldn't control.  Looks like your DH needs to get SS14 to the doctor for a checkup.  

To still be dealing with this problem. Eventually, so they say, it will go away. We have our doubts at this point.

Regardless of age.

Just the prospect of having to wear a pullup in public, to school, etc... has a miraculous way of fixing this kind of problem.

At least it did for us.

I actually fell out of bed in the middle of the bed several weeks ago. I found myself landing on the floor on my hands and knees.  When I fell it was between the bed and night stand.  I did bruise both my knees and the balls of my hands.  None of the floors in our condo are carpeted.

Once she expounded wiith a "What the hell???" my DW lost it in bellows of laughter.  I joined her once my sleep addled brain cleared.

In my defense....  I often sleep on the endge of the bed.  Over time the matress had walked toward my side of the bed and had about a 4-5inch overhang that neither of us noticed due to the hugely oversized quilt on our bed. Without being squared on the base of the bed (platform not a box spring) when I rolled over towards my side of the bed the matress edge flexed and down I went.  That is my story and I am sticking to it.

Some of these things need to be considered with some flexibility IMHO.  

While bed wetting at an inappropriate age can be infuriating, there may be some events/circumstances that need to be mitigated or considered.

My SS had a bed wetting relapse at about 6.  It was short lived, rapidly self corrected by the prospect of having a to wear a pull up to school the next Monday.  He had another relaps about 6mos later though that time was during a long international trip where we flew several long flights and were in different countries and hotels every few days.  My analytical slant ties that to the time changes and jet lag. His body did not recognize that it was bed time where we were compared to the time of day at our home with a 13 hour time difference.

Not sure if my logic holds medically speaking, but.... once we finished that trip I do not recall another event.

Does SS have any issues you know of? My son is 10 and still wets his bed Nightly.  He has had delays since birth and has learning disabilities though-not to mention other is the deepest sleeper I've ever seen. You can't wake him and ask him to do anything because he is zombie like and will converse with you then not remember.

However, my SD16 has ADD and literally crapped herself up until she was 14 (it was less often as she got older but still...) and it was because she would ignore her body telling her she had to go because she was otherwise occupied with something.  We literally had to 'bowel train' her at 14 as if she were a toddler that was sent into the bathroom after each meal or farting..to 'try and go'.  
our pediatrician also told us that boys sometimes linger with wetting the bed at an older age then girls . He seems a bit old but some kids need the reminders to commit it to memory of 'hey before I go to bed I should pee'.

Good luck though..I totally get it.

Make him wear them to school.  Bet it won't happen again.
