Is my two month teething?

[17c6]

I have a 2 month who is constantly chomping at her hands and covered in spit when doing so. Even after a feed, i first took it as a hunger cue. But she carries on even after a bottle. Ive upped her feed to see if she just wanted more and shes still doing it. She's constantly chewing her hands in her sleep like shes never been fed. Has she just gotten used to her hands or is this teething?

If I remember correctly I think they discover their hands at this age, but my DD also used to do this when she had trapped wind.
