Task:
Write down three things that you are thankful for. Discuss in depth with your child about what they are thankful for and why.
If you cannot write them, draw them then have a conversation about it.
i.e. I am thankful for the food that we have because there are some children in different countries that don't have any. Continue the conversation for as long as the child is leading it. If they ask you a question, perhaps research it.
