The binky..?

So my 16 month old still uses the pacifier, but only for bed time and nap times (has been that way for months now) never around the house, or out in public, even if she takes a nap out in public, no paci. Basically only when she's sleeping in her crib. I really wanna take it away completely, but don't know how to go about it... she never asks for it or gets upset when I take it away from her when I get her up from bed or her naps, so I feel like she'd do fine, but I'm also afraid she won't sleep as long, especially at night, without it. (she sleeps 7:30-7:30 straight) I'm due to have our second baby in end of Feb, and I'm afraid of making any big changes before then or around then, cause I don't want so much happening at once, adjusting to baby sister, no paci etc. but, I feel like if I take it away now, she'll forget about it by the time new baby comes. Any suggestions? Should I wean her from it now? How do I go about that? Cold turkey? Only naps? Leave me what worked for you, or maybe what you're having to do
