2 is far too young of an age to be able to understand addiction. When the time comes I’m sure she will inform her daughter about drugs and alcohol.
I was 5 when my dad died of a heroin overdose. My mother explained what happened in a very age appropriate way.
Throughout the years she told me more and more about it since I was old enough to understand. When I was 8 I learned more about what happened. When I was 12 or 13 I learned pretty much the whole story.
My mother always made sure though I knew somewhat what was going on, but the right amount of information for a young child to process. I’m grateful that she never left me in the dark.
I think it’s a good thing for children to know about addiction since it is a common problem.
Because eventually, no matter how hard you try and protect and shelter your children, they will eventually be exposed to that sort of thing.
And when that time comes you will want them to be as educated and informed about the topic as they can be.
However, 2 is far too young to understand this sort of thing.
