When was your baby able to suck on a pacifier by themselves?

My 2 month old loves her pacifier but she can’t keep it in her mouth on her own for more than a few seconds. We’ve tried Nuk, MAM, and Itsy Ritsy. She likes the Itsy Ritsy but I have to hold it for her. I was looking at the Bib pacifiers and thinking about getting them. Or is it just a matter of time and she should be able to take it herself?
