these toddler issues?

- DS1 has started saying "I don't love you", "I don't like you", and "go away". I generally tell him I'm sorry to hear that but that I love him or like him. Sometimes I tell him that's not a nice thing to say and that it hurts my feelings. Should I be ignoring it?

- DS1 has reverted back to eating with his hands instead of utensils. He can use utensils and will use them for soup or yogurt and other things that are necessary but won't use them for rice, macaroni and cheese and other things that he manages to eat with his hands. Should I trying to get him to use the utensils more or just leave him alone in hopes that it will pass soon?
