Wouldn't this be considered neglect in a child so young? A two year old missing a meal when he/she is hungry is more than punishment it's down right abuse. I don't think any child should have food withheld and especially not as a punishment, but a two year old? I would have a hard time not saying something.
As far as not going to the group that is something you will have to decide for yourself I don't think any of us can tell you what is right for you or DS.
