Answer: hello.. dear..Most of the time, this doesn't do any real harm to the vocal cords, the delicate bands of tissue in the larynx, or voice box. But chronic misuse of the vocal cords — such as repetitive screaming, yelling, or using the voice in an unnatural way — can lead to hoarseness.
Excessive crying is a common cause of hoarseness in infants. While all babies cry to convey their needs, some cry more than others, such as those suffering from colic. Crying for an extended period of time can cause the vocal chords to swell, resulting in a hoarse voice.
It's up to parents and other family members to encourage good vocal habits by setting a good example themselves. For example, rather than calling to kids from another room, walk into the other room to talk to them. Promote quiet times (perhaps for half an hour each day) and using an "inside voice" when indoors.
Reward systems that encourage these new behaviors usually are successful in elementary schoolers. Parents can offer stickers, tokens, extra TV time, a later bedtime, or similar incentives to get kids on board with the new, healthier habits.
