there is a saying that what adults do , childrens will also follow it even if its bad for them. i guess that saying can always happen on real events and it can happen to your child because they will follow your bad habits on which is playing a gambling. even if your good at hiding , time will come that they will always find out about it. so i guess in order to be a good parent and a good influence to other children. much better if we can avoid playing gambling if there is a children beside us, rather we will only do gambling in a private place or in casinos and online sites.
