Pacifier Dilemma

Was wondering if anyone had any tips or advice about this.

My daughter (5 months) usually will go to bed around 8:30 and sleep until 7. However, she wakes up multiple times in the night whining/beginning to cry and when I put her pacifier back into her mouth she will usually fall back asleep. It’s starting to get tiring for my husband and I, and I’m starting to get concerned about when we transfer her to her crib next month. Some nights we’ll do this 5+ times 😳

Any advice?
