1. Sometimes kids have different skin colors from their parents. It could be because they are adopted, or because their parents are different races, or because they have a step mom or step dad. It’s no big deal. They are still real families. There is nothing wrong or weird about families with different skin colors. (Insert examples from your own life here. Or have a come-to-Jesus meeting about diversifying your friendship circle).
2. When someone is adopted, their mom is just a mom. The person who gave birth to them is called a “birth mom”. Both of them are real moms.
3. It can be nosy or embarrassing to ask a kid if they are adopted or ask what happened to their birth mom, especially if you don’t know them. That could make them feel bad, so don’t do it. If you are curious, ask me about it and if I know the answer we can talk about it.
