It's normal for infants and small children to have numerous colds that can linger for weeks. Most colds and ear infections are viral and antiobiotics are ineffective and can actually help in the creation of superbugs. Docs will often prescribe them to calm the parent. Just relax and wait it out. If this is your first child, your anxiety may be much higher than is necessary. Believe me, by the time the third or fourth one comes along, you'll realize children just get sick - a lot - most of it viral.
