Help.

I have a 16 week old and she “sleeps” through out the night.... minus the fact that when her pacifier falls out she grunts and if you don’t fix it within 30 seconds turns into crying. *unless she’s in a deep sleep and doesn’t notice at first* As soon as you put the paci back in she’s out. But this has turned into me fixing her pacifier at last once an hour and then when it get closer to morning that changes to atleast every 20 minutes. I feel like I’m getting absolutely NO sleep. She’s also swaddled and that’s why she can’t fix it herself. If she doesn’t stay swaddled she will move around and keep herself up all night. — ANY ADVICE?! How can I get her to stop needing me to put the pacifier back in? Do I just do the cry it out method? TIA 😭😴
