I don't ordinarily post to message boards, but have found that I am always looking for information to help me make decisions on the various interventions that are out there. If it would help someone who's on the fence about this program to know our experience I'm happy to share. We are in the middle of our second ten week run through TLP. We have one son (just turned 5 yrs) with PDD NOS, which involves speech and language delay, auditory processing difficulties, social skills deficits etc. My other son (6 1/2) also has some auditory processing issues although much less severe. We started them both on the program at the suggestion of a very knowledgeable SLP in Dallas. The changes have really been amazing. We are now fully potty trained (thought it would never happen), he is now speaking in full sentences much of the time, his awareness and processing of his surroundings has increased so much, he's asking questions and he's much more able to have "back and forth" conversations. I also use it and have been pretty meticulous about keeping records each day of what module we're on and how much time they listen to make sure we're getting the maximum benefit. Their school does offer it as part of the reading intervention program, but I think the consistency we're able to achieve at home has made all the difference for us. There's no question it's expensive and we agonized over the decision, but for us it's been worth the expense.
