You can choose a gift that he wants or that you want to give, but it must be one that he likes. If he doesn't like it, it's useless. I have a few ideas for reference:
1. Give him a music box or MP3 or something like that, so that he can listen to music. Listening to music is very beneficial to the growth of children, especially elegant classical music and children's songs with happy rhythms. Experts say that the more music a child listens to, the more elegant he will be in the future.
2. Leave a beautiful childhood for your child and use a camera to record the growth of your child. On his birthday, give this special gift full of deep affection to your child.
3. On his birthday, you can take your child to the suburbs to play, experience the beauty and enthusiasm of nature, tell your child about what you see, and take your child to a big meal when you come back. He will definitely be very happy.
