She is probably about six months old.
Explanation:
From the time of birth, babies tend to grasp things in their hands as it is a basic reflex with them. But within six months they are able to hold things with a grip in the hands. Babies around six months tend to grab things by both hands. Within the time of 6 to 12 months, babies tend to strengthen their hands and enhance their activities of grasping objects. Hence, firm gripping can be depicted as a milestone which a baby reaches when 6 to 12 months old.
