Pacifier help...

Rebecca • Married to my high school sweetheart. Currently have 2 children Xavier Cole and Mariah Nicole.
How do you know if a baby's pacifier is too big? And what happens if it is too big but don't know it? My daughter is only 2 months and the 0-3 pacifiers keep falling out. I gave her a 6 month pacifier and she loves it but idk if it's safe or not.
