Creating multiple child records based on a # field in the parent

Hello Community! 

Okay so I am looking to set up a system where once a new record gets created in a parent table that includes a numeric field in the record, it will create "X" number of child records equal to the value listed in the numeric field ID.  Is this possible?

I am sorry if my description makes no sense.  An example is below.

Contract Record is Created (Parent Table) with a field in the form that is titled "# of related contract amendments" and say that field is equal to 6.  We would want 6 records created in a child table related back to the parent. 

What is the best way to do this?  Pipeline?  Automation?  I am just not sure how to get the # of related records created to equal exactly what the user inputs into the numeric field within the parent record.

Any help is appreciated!​
