New Year's Day is a new beginning. Don't let your brother bring his bad mood into the new year. It's a good idea to give him a small gift to make him feel better. Here are some suggestions:
First, give him a gift he wants. You can ask him directly. If it's not too much, you can properly satisfy his wish. I believe he will be very happy.
Second, give him a useful New Year's Day gift. You can give him a good book. Knowledge is never too little. It is also a kind of encouragement to him. You can write your message on the title page of the book.
Third, give him a creative gift. A big teddy bear is a gift that children like. You can give him one. He will definitely like it. You can also give him a sunshine piggy bank, which can store the magical gift of sunshine. You can also give him a real doll of him. All of them are good gifts.
