Hi Barbara.... welcome to WikiTree :)
I agree with Kristina in that each person should have their own profile, and that entering them one at a time is the best way.
However, there is no obligation for you to create the profiles if you do not want to. Another option for recording the information you stated is to put it in the biographies of the parents. Someone else in the future could pick up where you left off and create them later.
Have a super day!
