We are in the process of getting a diagnosis for our 1 year old son. They want us to take him for blood work and a urinalysis. The blood work is no big deal, but how do you get a urine sample from a baby in diapers? We were given a list of tests, how much urine we needed for each and urine collection bags and bottles. One of the test requires a first morning urine sample. I tried to wake him this morning and put the bag in his diaper, but they constantly fall off or the urine leaks out into the diaper. I don't know how the heck this is going to work. Has anyone had the urine collected any other way?
