Sorry about my misunderstanding.
I just want to clarify that "day 1 Left brain program" & "day 1 right brain program" are different not only in speed but also in contents. But If you finish 20-day program for each program,your child would see same contents at the end.
I like this way better.

"Emma's mom" is the mom of the girl who can read at 2 years in their testimony. I asked her about this mom's method.
Anyway, this is the e- mail response that I got from Michelle from babybrain workout flashcards.
I am pleased to be able to help with your queries. Here are my answers:
1. Emma's mom actually chose to show left and right brain programs on separate days. So her schedule would go like this:
1st day - left brain, day 1
2nd day - right brain, day 1
3rd day - left brain, day 2
4th day - right brain, day 2
... and so on and so forth.
There is no right or wrong way - the important thing is consistency. As long as the parent is consistent in his/ her approach, it does not matter which program goes first or if they are shown together.
2. It is up to you which program (left or right) to start first - if you are showing both programs on the same day, you can start with left brain first on the 1st day and then start with right brain on the 2nd day - just to see if there's any difference on your child. Most children prefer the right brain program because it sounds cartoonish (like chipmunks), so it depends on your child. But research shows that the younger you start your child, the easier for them to adapt to the training.
3. Yes, if your child shows interest in musical instruments for example, do not show the next day's program on that same day but you can show the individual subject (in this case, musical instruments) for your child after the day's program as a reward. You don't have to let your child watch the individual subjects if she/ he does not show interest in that particular subject - the reason is because all flashcards have been shuffled into the 20 days' programs. So as long as you follow the program, your child will be subjected to all flashcards eventually.
All the best in a good start for your child! We welcome testimonies - hope to hear from you again soon.
