Great grandchildren and Great Nephew/Niece's

[Tizzkm]

So I'd like to ask if you would treat your great grandchildren the same as your grandchildren?
I have. 9 grandchildren. And two great grandchildren. The two great grandchildren I rarely see or have a close relationship with. Should I be spending the same amount on them as my grandchildren on their birthdays and Christmas? I feel family that are great such as nephews and nieces I don't know what the protocol is. And if you had 10 nephew and nieces do you buy all their children presents too?
Where does present buying stop? Also do people stop at age 18? Help

My grandparents have 14 grandchildren and so far have 21 great grandchildren. Us grandkids stopped getting money/gifts when we had our children. As far as I'm aware, the grandkids without dc get a tenner and those with kids get nothing, but the great grandkids get a fiver.

In our family, we all agreed that the last present for nieces and nephews was when they turned 21.
Not cost so much as just not knowing what to get them. Then the awkward decisions about partners, and when does a new boyfriend / girlfriend start getting gifts as well and so forth. When I see my nieces and nephews I will sometimes treat them to a meal or a coffee and a cake, or, if I happened to be seeing them on their birthday I might take some flowers or some chocolate or something, but there is no stress about "I wonder what they want / if thy have got one of these / what size they are / will they like it / etc". No remembering in time to go shopping and get posting. No issues about deciding when a partner is "family".

Own children and grandchildren and Gt grandchildren, I presume is different, as will (I expect) always want to get them something.

In my family we’ve always stopped buying for any child when they reached 18.
When the great grandchildren came along they got a money gift when born to go into savings account.
Then just cards, no further gifts.
