In Isaiah 7:14-16
14 Therefore the Lord Himself will give you a sign: Behold, the virgin will conceive and give birth to a son, and she will name Him Immanuel. 15 He will eat curds and honey at the time He knows enough to refuse evil and choose good. 16 For before the boy knows enough to refuse evil and choose good, the land whose two kings you dread will be abandoned.
and in Isaiah 9:6
For a Child will be born to us, a Son will be given to us; And the government will rest on His shoulders; And His name will be called Wonderful Counselor, Mighty God, Eternal Father, Prince of Peace.
Are these passages speaking of the same child?
