0-7 years old is the fastest period of children's brain development. If we can enrich children's life at this time and give correct education according to their age characteristics, we can accelerate children's intellectual development and lay the foundation for the formation of good behavior habits and personality quality.
So 1 year-old is more appropriate, not too early, you can cultivate children's interest first.
6 1aoe is very popular in teaching children to read.
