My daughter is 8 months old and I don't know how to react when she does something wrong. Lately she really wants to get in the dog food at Grandma's house. We can move the dog food when we're there, but I don't want to make a habit out of avoiding bad situations, I would like to teach her that we don't need to play in the dog food. So when she goes for it I tell her that she doesn't need to play in it and pick her up and move her. She just goes right back to it. Should she be understanding what I'm saying? I don't want to be like my sister screaming no at her children like they're dogs. How do you (and can you) discipline an 8 month old?
