2 finger sucking

Hi My Lo is 11 month old, she is sucking her 2 fingers most of the time. Since 8 month she started sucking when she wants to sleep. But now she is sucking most of the time. Please suggest some techniques that will help me to stop that. Feeling bad that it might affect her teeth alignment. #pleasehelp #advicemommies #advicepls #firstmom #1sttimeMomHere #1sttimeMomHere #suckingmyfinger
