Is it possible for 11 wk baby to start teething? My girl recently is very cranky and cry with no reason. Playing with her saliva and put whole hand in her mouth. Today she never nap and keep want to suckle.

It could be some other discomfort too? my LO had indigestion and she couldn't sleep as well. Putting hand in mouth is a self soothing mechanism for them. But that being said, teething can happen early but not sure u should link these symptoms immediately to teething without exploring other possibilities of what may be bothering her
