Three-or-four-yea-old children are able to think logically. If you communicate with them as an equal individual, they can accept and understand that, and that can help dissipate un necessary doubts the child may have (doesn't Mom my love me as much?).
三、四歲的孩子就很能「講理」了，把他當一個平等的個體來溝通，他會理解的，也可以減少孩子不必要的疑心（媽媽是不是比較不愛我？）
