Too many siblings?

<p>The Common App only provides space for up to 3 siblings (I have 6 total), and then says to list any additional siblings in the "Additional Information" of the Writing part.</p>

<p>Is it necessary to list all of them?
I don't know why this question is being asked & I especiallydon't see why colleges need to know all their names & ages....</p>

<p>Yes, you should list all of your siblings in the indicated area.</p>
