Okay, so my 2 1/2 year old little boy has been potty trained for 9 months or so. We have not had any accidents in quiet a long time. About 2 weeks ago he started not wanting to go potty even when he told me he had to and now I have to practicaly drag him in to the bathroom and force him to go. Along with this, he has been saying his tummy and pp hurts. So we happened to be at the md and I mentioned it, she did a quick urine test at the office, which was negative but she wanted me to take his urine in to the lab for a second look. Well, I got busy and a couple of hours later his urine had separated, so the yellow part was on the top and a whote powdery substance was on the bottom. It is about 40 degrees here, so there is no issue with heat what so ever. I have never had this happen before and not even with him. On trips, we have our boys pee in bottle all the time and I have NEVER had this happen. Anyone heard of it before? His accidents in just 24 hours have become more frequent and he seems not to be emptying his bladder completely. HELP!!!
