When Annah gets hurt feelings she always wants to make up after or looks or reassurance. She'll come up to you and give you a hug and say "I love you too!" She always adds the "too" even if you don't say anything before.

When I tell the kids "I love you" they say "I love you too". Then I say "I love you three, I love you four (..sometimes adding, "I love you more").
