Anybody have any good tips for assisting a brand new surfer catch whitewater waves and attempt to stand for the first time?

I'll be helping my niece in a week or so.  I have a 7'6" soft tech foam board which has plenty of volume but hoping it won't be too short.

Should I try to push her into the white water waves or just help keep her in position and have her paddle into it on her own or have her paddle and give a little push if needed?
