Are you interested in right brain training for your baby? if you are interested in right brain development then I suggest that you can reference teachings from makoto shichida. All of the above schools mentioned actually mix right brain and left brain development together.
If you read on some right brain development methods from makoto shichida's teaching, you will realize that the way to teach your baby to purely only uses right brain is very hard. Thus sometimes schools try to train right brain with some left brain lessons.
If you are really in to right brain development for your baby, you can try shichida but do just take their lessons as guideline for your baby's daily training. Or you can try right brain networks.
