What do you do if your family insists that Christmas gifts are only for kids but you like to give them gifts no matter how old they are?

Answer 1

Then you should feel free to buy them gifts, but not expect them in return. Sometimes people say that gifts are only for kids because it is too expensive to buy gifts for everyone, so you should be respectful of that possibility and rejoice in the giving if that is what you choose, but not expect everyone to be like you. :)

I wouldn't give gifts if the person asked me not to, if they don't want you to give them a gift then there must be a reason for it.
