My little one was a paci addict, it drove me nuts!!! LOL I allowed her to keep it until 3 months, after that she began to spit it out during her sleep and would wake up when she realized she didn't have it, and cry (vicious cycle). VERY DEPENDANT on it, i decided i had to give it a try and teach her how to fall asleep on her own using shh/pat, she cried but it worked. Now we don't' need it - your LO is pretty young, suckling reflex is very strong now - to young to find her fingers yet. The older she gets the harder it will be to get rid of the paci, it's really up to you. You can teach her now or wait a bit if it's not a big deal for you to deal with shh/pat & crying later...I think it's after four months that habits really begin to be burrowed. Well no matter what, crying is going to be involved - just comfort her. Good luck....
