I don’t know where I heard or read it, so take my explanation with a grain of salt. Most poisons taste bitter, so avoiding bitter tasting things means avoiding poisonous things. Since children have a smaller body weight, the lethal dose is smaller for them. As go grow older, your body mass increases and so does your tolerance to poisons.
But I am not sure why we would not want to avoid poisons in general even if they were not lethal any more.
Because some plants use small amounts of those poisons to avoid being eaten. So losing some of the aversion to the taste gives you a wider variety of food sources once you can tolerate the poison enough.
