I have 2 grandsons, same Dad, their language skills are so different. The 5 year old was a very late talker but now corrects us. He has superior language skills. The 3 year old spoke early and at this point is difficult to understand. Go figure.
That is weird, usually the first has very good language skills, while the second one does not, the first one usually inteprets the second. My daughter who is the #2, points at what she wants and then claps... when she is hungry she rubs her stomach, points at the food she wants and then claps.... It's all actions with her, though she can talk and hear.
