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.
If a court order gives certain custody or visitation rights to a party and the other party fails to obey the order, the complaining party may file a petition alleging a violation of the order. parent seeking to visit with a child may file a petition in Family Court against the person or persons who have custody of the child. Custody and visitation matters are often heard together within the same hearing, but a visitation petition may also be filed as a separate matter.
