My daughter was using her pacifier until she was 2.5-years-old (eek!). She didn’t have a problem when she didn’t have it at daycare (started at 9 months) but she needed it to fall asleep at night.
We went cold turkey as well a month ago and like you experienced, it takes longer for her to sleep and she cried a lot, but things are generally fine. She hasn’t sucked on her thumb as a replacement yet.
I’ll share this on my Twitter to see if other parents can share their experiences as well!
