Hello,
Welcome to BrillKids!
You can definitely start and continue to show Little Math and Little Reader on the same day(s).
I usually show my son both Little Reader and Little Math twice a day.
I started Little Math and Little Reader the same day.
The program recommends twice a day five times a week. But you can make any schedule you want.
You should design your schedule according to your baby's interest and time you have available.
The second lesson of the day is a review.
It also depends on how your child reacts to the programs.
If your baby starts to show signs of disinterest that is when you should cut your lesson short and continue later.
If your baby is engaged in the programs there are extra files you can download to make the lesson longer.
