Tylenol, gripe water for his tummy, and chamilia works good!

Tylenol frozen breast milk or formula teething toys teething tablets teething gel if you're breastfeeding let her teeth on you.

Frozen wash clothes
Teething toys (you can also freeze them)
Tylenol on bad days

Teething tablets, teething gel if she is old enough I don’t remember the age and on the bad days Tylenol

Frozen washcloths were my kids favorite they would never do the teething toys or anything

Hide in a dark hole until it passes. LOL

But really...teething tablets are amazing. And on the bad days, if her gums are visibly swollen & red, ask your pediatrician about a Tylenol dosage for those days.
Also, wet a corner of a wash cloth & put in the freezer & let her chew on it.
