Hi, My 6 month old baby is very much interested in sucking her thumb. I have tried using mittens but still her hand goes into her mouth. She always has her finger in mouth n don't cry for feeding, so I don't understand if she's hungry or not. Also while sleeping, unconsciously she will take her finger mouth, and sleeps..I have no clue to make her forget about it. Will she get used to it even after growing or should I take any other step to stop her from doing this ?
