Medicare Part B does not cover routine hearing exams or hearing aids. Medicaid, however, may cover some of the cost of hearing aids, depending on the state you live in. That's because each state operates its own Medicaid program, and each program has slightly different rules and coverage.
Research shows that infants display behaviours that are important beginnings for theory-of-mind development (see details in Mooreâs and Sommerville âs papers in the chapter on social cognition 9,10). By age 2, children clearly show awareness of the difference between thoughts in the mind and things in the world.
Each child develops at his own pace, but talk to your child's doctor if your 3-month-old: 1  Can't support his head well. 2  Can't grasp objects. 3  Can't focus on moving objects. 4  Doesn't smile. 5  Doesn't react to loud sounds. 6  Ignores new faces. 7  Seems upset by unfamiliar people or surroundings.
