We cannot really tell when can a baby possibly start teething, however, there are signs that will help us to determine when she's on the way. Regarding my baby’s experience, she started teething as early as 5 months old. Her first pair teeth burst out at the lower, central portion, followed by the upper central pair teeth, and many more. During this teething stage, she behaved so strangely. Drooling, ear pulling, whining are just a few of the signs she went through.  So, read more of the signs I'm going to share with you.
