Asalaamu alaikum bro
Yeah i get you totally, surprisingly many born muslims revert back to Islam (even though they don't really leave Islam) - they might turn to Islam whole heartedly when they ponder over it deeply.
The problem that some born Muslims face is similar to many reverts aswell, and their parents become scared that their child is becoming either 'too extreme', or is straying away from a deviated sect that muslim family might be following.
So in reality, even born muslims go through similar. Their parents can be on either side of the scale, i.e. too secular or too stuck up in the teachings of a deviated sect which promotes acts which are totally contradictory to true Islamic teachings (probably because they too were brought up following these false teachings too.)
So don't worry too much, those who follow the true guidance, they are usually the minority throughout history. And this shouldn't put us off, rather we should be thankful to Allah that He has guided us.
