I use Avent teats since the birth of my son. They are of good quality, long wear and are resistant to many cleaning. However I find the age of use is not always true, these pacifiers to 4 months still too fast flow for my baby. This is the only negative I found them! Practice as if mixed with other nipple sizes, there are size marked on the side of the nipple, easy to spot to find that which we seek!
