In my opinion if children should follow some rules, then parent need to follow some rules too.
There are some rules for parents:
1.Always lend an ear to your children
2 Never shout at them in public
3 Respect your children's opinion
4. Never have doubts about them
5 Take decisions, only when you have already discused that with your kids
6 Trust them,never spy on them
7, Have as many talks as possible
Find some common interests and activities with your children
