The Eustachian tube connects the throat and the middle ear (the site of a typical  ear infection ) and allows air to travel between them and equalize the pressures. When the Eustachian tube is temporarily pinched off, pressure can build up in the middle ear.
Visitation is a matter of state law, but generally speaking, every state allows parents to exercise a reasonable amount of visitation with their children, which generally means enough time to establish and maintain a meaningful relationship.
Visitation is viewed in North Carolina as a lesser version of custody. Hence, the same principles apply to custody as to visitation in regard to the best interests of the child, parental rights, the childâs wishes, and the discretion of the trial judge.
