2 1/2 year old suddenly sucking thumb?

Hey Mama’s, so my 2 1/2 year old has started sucking her thumb. She has NEVER sucked her thumb. So I’m confused as to why she suddenly is? I am currently 30 weeks pregnant, idk of this has something to do with it? But it’s becoming a habit that I’m trying to get her to break. Any ideas or suggestions?
