Parenting Tips for Your 4 Month Old Baby

A baby's first teeth often come in at about 6 months of age, but some babies get them as early as 3 months of age. Some babies won’t get any teeth until after a year. The age doesn’t matter. Once she starts, your baby will teethe off and on for months.

Here are some signs to look for:

  • Your baby will want to chew on everything.
  • She will probably drool more than usual and may be fussy and cranky.

As teeth push through the gums, your baby will feel some soreness. Chill a clean teething ring in the refrigerator, then give it to your baby to chew on. If your baby has a fever, vomiting, diarrhea, or other signs of illness while teething, call your doctor.

The American Dental Association encourages that parents:

  • Begin brushing the baby’s teeth with a little water as soon as the first tooth appears.
  • Do not use toothpaste until your baby is at least 2 years old.
  • Take a child to a well baby dental checkup by her first birthday.
