Cuddle the child in your lap with his head raised up. A child should not be put to bed with a bottle. A bottle should not be propped in bed. Those practices may cause the liquid from the bottle to go up a small tube leading to the middle ear, causing middle ear fluid. Keep children away from smoke.
Cigarette smoke increases a child's chance of middle ear disease.
If possible, put children in small rather than large groups of children. These suggestions will help all children listen better. Get your child's attention before speaking. Face your child and speak clearly with a normal tone and normal loudness. Use visual cues such as moving your hands and showing pictures in addition to using speech.
