At what age do grandchildren give their grandparents presents themselves?

Yes if someone buys their GP a gift that’s wonderful but I think it’s very immature to expect it

We don't expect anything and we are not immature.

My granddaughter now age 16 has always bought me and late DH Christmas & B'day presents. When young of course they came via parents but since being age 10 or so she's always chosen them and paid for them herself and they've always been very thoughtful. She also always sends thank you letters.

My children are 20 & 22 at Uni, my mum is 97 & lives with us. My kids buy my mum themselves, they have since they were about 15 with their own money.

I taught my grandchildren when they were young to give their parents little gifts at Christmas and birthdays.
And their parents taught them to give gifts to grandparents
I get lovely gifts from 3 out of my 4 grandchildren. The other one ignores Christmas altogether as she hates it.

We have received gifts from our 26 year old granddaughter since she was 16 and started her first part time job and this year we received small gifts from our two youngest grandchildren who are 16 and 15.

I love it when g.children give me something they have made themselves. So, I have paintings, embroidered pictures and other forms of handiwork, all proudly displayed in my home.

I would not expect any of them to give me something they have purchased until they are reasonably well established in employment.

Much to my very pleasant surprise my eldest g.daugher's partner gave me a lovely little present this xmas - a box of assorted teas. Yes, he is post-graduate and employed, but it was very unexpected.

I have never understood the idea of parents paying for 'presents' from young children. If the child wishes to give anyone (including their own parents and siblings), then they need to be taught to save up from their pocket money for that purpose.

If their parents had never prompted them to ‘buy’ granny a little gift from when they were small, I can’t see it will happen for you now.

Here it depends on the parents. Son’s children have enjoyed buying gifts since early teens with saved pocket money, then weekend earnings. It’s lovely because you never know what to expect. Adult gd gives the most wonderful presents but buys them through the year. However daughter’s late teens offspring never buy any thing, it’s as much as a surprise to them when gifts are opened as it is to the recipient 😂. I suspect the gifts come from their mum’s present drawer.
