Could somebody please tell me ,I am updating my SEF from old to knew.

One of thecquestions at the beginning asks about the child's likes and interests.
Now when I first wrote my SEF three yrs ago the child in question was 9 months old and didn't talk and kinda liked pepper pig.

She is now 4yrs old very chatty and I know a lot more about her likes and dislikes, so do I delete what I wrote about her when she was 9 months and fill in what she's like now ????
