Generally, when children turn one, they will give them longevity locks, jade pendants and other accessories as gifts, because they have good meanings. Some people also give red envelopes directly, but considering that you are giving a gift to your boss's grandson for his first birthday, this is definitely not okay. So my suggestion is to choose according to the type of boss. Here are some suggestions for you, I hope it will be inspiring to you:
1. If your boss is a "carefree type", for example, his company is large and financially strong, then the first birthday gift for his grandson should be meaningful, rather than "fawning" and giving expensive gifts. You can give your child some gifts that have growth significance, such as custom-made real-life dolls and crystal music boxes with your child's photos. When the child grows up, it will be fun to take them out and look at them. I believe your boss will like such gifts.
2. If your boss is a "unique taste type", for example, he has many hobbies, and his hobbies are very unique, then the first birthday gift for his grandson can be something related to his hobbies. After all, the child is young and there are not many gifts to give, so it is better to give him a gift! Nowadays, it is popular to give wine as a gift, which is both ornamental and practical. You may also consider it.
In short, the gift for the boss' grandson's first birthday should be based on "value" rather than "price". Only in this way can the gift be decent. After all, the boss is richer than you!
