YSK that in parenting, HOW you talk to your child matters - it changes their brain. Talking TO or AT your child, even if you are exposing them to many words, is less important than having engaging conversations WITH your child, ideally where your child takes the lead.

YSK說，在養育孩子的過程中，如何和孩子說話很重要--它會改變他們的大腦。對着孩子說話或對着孩子說話，即使你讓他們接觸到很多詞彙，也不如與孩子進行引人入勝的對話重要，最好是由孩子來主導。
