How to take binky away???

Po

My 27 month old loves her binky. 🙄I'm currently TTC #2 and wondering if I take her binky away now (which I'm sure will cause major problems) and have a new baby, will she always try to take the baby's binky? Will 9 months of pregnancy be enough for her to get over it and forget about it? assuming I get pregnant soon...

So, I'm pretty sure I can come up with a way to get her off the binky, but I'm just wondering if it will be wasted effort if she just gets addicted again when new baby gets here? Or should I wait and de-bink both kids together?
