what to do if baby is licking her fingers??

A. Because finger sucking has a soothing and calming effect, some babies will develop a habit that can be very hard to break. In the second month of life, babies continue to have a strong sucking reflex. You may notice your baby likes to suck on a fist or a few fingers. This is one of the best ways babies have of comforting themselves. At 2 months, your baby doesn't yet have the coordination to play with toys.
