How did Suzette and AB feel about living in her shadow?

Don't get me wrong, Im sure they were a close family and supportive towards each other at the end of the day.

However, it's not uncommon for siblings to feel somewhat left out when one gets a load of attention. Did this ever lead to occasional jealousy, arguments, etc?
Especially since they ALL started out the same way forming a band and playing At restaurants and carnivals as kids.
