Thumb sucker advise!!

🖤S

How did you get your thumb sucker to stop sucking their thumb??

I tried really hard not to have a thumb sucker in the first place but here we are lol my girl is 19 months and I'm not sure how to get her to stop.. I can pull her thumb out about 4 times and after that her heart breaks cause she just wants her thumb 💔 ugh!
