When giving gifts to children, you should be careful. You can't buy food now, you can only drink milk powder. You should also be careful when buying toys. At least you can't play with anything now. You can prepare some dolls for him in the future, such as Barbie dolls, Snoopy, Winnie the Pooh, Shy Bear, Teddy Bear, all of which are good choices.
You can also take a photo of him when he was a child and order a real doll online. It is a very memorable gift. When the little guy grows up and asks who is older, you can laugh and say that this is you when you were a child.
Or buy a delicate little mirror that can not only be used by the kid, but also for his mother before the child grows up. It really kills two birds with one stone.
In addition, I will introduce you to a sun jar, which is very suitable for children. Its principle is unique and interesting, which can stimulate children's desire for knowledge.
I hope my suggestions can give you some inspiration.
