唔打人, 叫一陣無所謂啦. 唔使介懷, 唔好覺得失禮. 有d人會用岐視既眼光睇 小朋友尖/樓計/訓地/狂喊. But I think it is very very normal for kids, no shame.
Don't give pressure on yourself due to kid crys/scream!
尖叫 = 心急表達有d野佢唔like. but she can't speak but she 好心急想講. 你應佢一聲你知啦米得囉. . 基本上過一排識表達唔會架啦.
My son is sometimes screaming too and I will teach him no need screaming and you can tell other kids / anyone that you don't want / you can't accept / Or just say NO, sorry. 佢宜家好叻講 "行開啦, sorry 唔比你, sorry唔得. He likes these sentence even they are quite difficult to say.
