Cheryl,
A warm welcome to you and your son! I am sorry to hear you were forced to give him up for adoption at birth.. I am also adopted, but from my understanding I was relinquished voluntarily. While I won't pry into matters you want to keep private, I am curious about how you regained custody..but if you care to answer that.. you can easily PM me. Where are you and your son from? I am from northern MI, and I actually have worked at a special needs camp 4 hours west of here, offering both a summer children's therapy camp, and an adult recreation camp. If you are interested, PM me for details.
I echo what Inconimiss said about using premium brand diapers if possible. In my own expereince with moderate to heavy mixed urge/stress/overflow incontience, I have found brands like Abena, ConfiDry, and Absorbency Plus excellent for extended wear use, while I use attends breathable for day to day use on a change-when wet basis. My situation is obviously different than David's, as I have some bladder control, and full bowel control, so far... knock on wood..
What is your son's waist size? That is actually an important consideration, because not all premium diapers are available in size small. If you are looking for an excellent source of premium diapers.. this is my one stop shop:
http://www.xpmedical.com. The owner is himself incontient, and that gives him excellent insight and he can give great advice on product selection. His prices are the among the lowest I've seen, and his products ship very fast. I encourge you to give them a try! You can also get sample packs of the diapers he carries on his site.. hope this helps!
Peace out!
Rob
