When babies are teething, they're generally miserable from the pain, swelling and tenderness in their gums. Here are suggestions from the Nemours Foundation to help comfort little ones who are teething:
Use a warm, wet cloth to wipe down baby's face and remove any drool.

This may help prevent a rash.
Offer baby something soothing, such as a teething ring or a wet washcloth that's been chilled in the freezer for about 30 minutes. Be sure to wash the cloth after each use. Treat baby to a gentle gum massage, making sure to use a clean finger. Ask your doctor if it's safe to give baby acetaminophen. Make sure your doctor approves a specific dose and frequency. Never tie a teething ring to baby, especially around the neck, as it could cause strangulation.
