when I looked at this thread now I remembered that days ago I have seen very strange things in my city, I see children who are only 6 years old and others who are 8 years old having a cell phone and playing games, and these children spend most of their time days playing on the phone and then without a doubt they will start playing games of chance, because these kids on the phone do research and when they search about games for phone they will find games of chance and as they grow they will enter the world of gambling and they will not talk nothing for parents, I think it's a big risk to give a 7-year-old a phone. in the same way that a parent should not take their child to the world of gambling, this is not a good thing.
I do even see as early as 5 years old which it isnt really that surprising in todays era considering that we are on high-technology era where people could easily have access with these things.
This do simply puts up that parenting or guidance does really play such important role on childrens growth.If he get used to into things when he was young or simply
do able to see it on people around him then much sure that he would really be following those steps.
