How to use little reader, math, music

Hi there! I’m just starting on little reader on my 5 month old boy! I’m wondering how do I use the mandarin, English, math and music.

I don’t want to overload him with too much and take away the joy of learning together.

Anyone care to share how you manage lessons?

Also, what Is the key difference using flash cards in sets of 5, 3 sessions daily versus little reader?

Many thanks & happy parenting!
