We recently got another piece of the puzzle when our daughter was tested for ADHD and it came back extremely likely. The test was given by the school psychologist, along with questionnaires filled out by me and the kindergarten teacher. All three came back with the same results--highly likely ADHD. I agree with your feeling that you are being "fobbed off" by the pediatrician. Attributing it to the birth mother doesn't give you a diagnosis and a treatment avenue. Although nothing has been the "magic potion" for our daughter, everything we've tried has provided some improvement in her behavior, function and well-being. The Feingold Diet caused the biggest improvement in behavior and toileting, therapeutic listening helped to lower frustration and impatience, OT has helped with balance and surprisingly speech, probiotics have helped with focus/attention span, and our most recent find was an Australian book called Ten Gems for the Brain (ebook) which has really been helping with learning and reading. Last summer we had to fight to get her to do one workbook page per day and after a month of the exercises in Ten Gems, she's asking every morning to do a page from six different workbooks, recognizing more words and beginning to read. I'm not saying you shouldn't seek other diagnoses if it will help you get more services, but there are also additional things you can do at home to move him forward (but I know it's exhausting ) You're doing great, and I always appreciate your posts and input!
