How to get my 1yr old to get her fingers out of her mouth?

Help please! I’m trying to figure out how I can get my 1yr old daughter to stop putting her fingers in her mouth, especially when she cries. This has been causing her to basically force herself to throw up and idk what to do about it. I’m currently 19w pregnant with baby #2 and it’s so hard to keep up with her already and now on top of it I have to clean up her throw up (which I know could be prevented). I’ve heard of putting garlic or chili on the fingers but I don’t want her to rub her eyes and get it in there so I’m completely clueless rn.

Any help is VERY appreciated 🙏🏻
