Good idea for the shelf, but I still think 2 is way too young for this. They don't understand the concept that they need to eat full meals and that they can't snack right before dinner so that they are hungry enough to eat a proper meal. I knew can't.. My lo oftern asks for snacks around 4 and I have to say no because I know that he won't eat his dinner and him being a bad eater this is important
It would worry me e could be helping himself to food when my back was turned if it was close to meal times, and I like to know what he has had so I plan his meals. Also I know with my lo the new experience will be fun and he would do it even if he wasn't hungry it would be a game
I'm all for this in a few years but right now I would lock it.
