You can show your baby some colorful pictures, and your parents can read a book, true or false, and he (she) will remember your appearance. You can also consciously repeat some children's songs, poems and the like. Although the baby can't say anything yet, the baby's little head can remember something.
I still suggest you buy some auxiliary educational supplies, such as reading pens. That's what my children do. I bought a set of early education products when he was 1 year old. You can find the most suitable education for China baby through Baidu search. I hope I can help you.
