My oldest was born with teeth, so yes, it's entirely possible she is teething. It can take a while from when teething pains start to when the teeth pop out, also. You might have a couple of weeks of teething, then nothing, then out pops a tooth. She may be drooling a lot, maybe even have a very low grade fever or have mild diarrhea. We tried Hyland's teething pills and sometimes they did help. We also did frozen bagels and the teething rings you can put in the freezer. No orajel though, because we were told that can actually prolong the process.
