Babies can begin teething as early as 3 to 4 months of age, which is a period where the teeth begin to sequentially erupt. The pain that children feel varies. Some babies can become irritable while others donʼt seem to be bothered at all. Symptoms of teething are swollen gums, drooling, crankiness, difficulty sleeping, and loss of appetite. You can help to alleviate some of the symptoms of teething by gently massaging your childʼs gums with a clean finger, a small cool spoon or a wet gauze pad. A teething ring may also help.
