Advise: Serious Sucking

Crystal

Over the last five days my daughter has started to want to stuck on something almost constantly.

1 - It seems like a reasonable age to start teething (almost 3 months) but she's sucking, not chewing.

2 - She's really bad at using a pacifier. She prefers a pinky but will take a pacifier sometimes. When she does it keeps falling out and make her angry. How do you teach a baby to hold onto a pacifier?

3 - Sucking on our pinkies has gotten so needed that i have to trick her with my pinky before she will breast feed.

Any idea what's going on?
