My LO is 20 months. She still has her pacifier ONLY allowed in her crib. Recently, I bought the  Lily Method to try and get her off the pacifier. So I haven't been as hard on her with having the pacifier outside of her crib. Without the pacifier she is usually crabby and fussing quite a bit. Today, I have noticed she is calm, playing on her own and more content. I still would like to get the pacifer away from her before it does effect her teeth. But why is this?! Why is she so much calmer with it ?!! I want her to be like this everyday...
