#AskTheExpert hi doctor, my baby is nearly 5 months old, she is sucking is fingers very often, can we feed her some food now, when we eating she is looking the food curiously?

A. Babies have natural rooting and sucking reflexes, which can cause them to put their thumbs or fingers into their mouths — sometimes even before birth. Because thumb sucking makes babies feel secure, some babies might eventually develop a habit of thumb sucking when they're in need of soothing or going to sleep.
