Pacifier for toddlers

Melody • Mom to soon to be three amazing daughters❤️❤️

My daughter did not start taking pacifiers until she was 1 and mostly uses them to go to sleep. She has increased in wanting them, but I feel horrible because I have been giving her Avent Pacifiers since those were her favorite and found out they are to be used until 18months. She's 21 months im needing to find a replacement, any suggestions on what pacifier is good to use for those over 18m???
