My LO will be 2 months old this Friday the 11th and has started chewing on her fist. At first I thought she was just discovering her hands but today I noticed that she has started to get fussy/uncomfortable at the same time she puts her fist in her mouth. When she started crying I swear I saw what appeared to be two white marks where her first set of bottom teeth are supposed to come in!! All of the online resources I’ve look at state that they don’t start teething until around 6 months of age!!! Has anyone heard of teething this early??
