Birthday gift - have I spent too little?

[SavannahKT]

Hi everyone!
My 3yo DS was invited to a birthday party by a friend from school. For context, we live in a small town so I knew this mum before our kids started school together (we’re not close friends though).
Anyways, birthday boy has a brother, almost exactly 1 year younger, so we were actually invited to “X and Y birthday”.
I have purchased a €50 gift voucher from an online store, but now I’m starting to think that it might be a bit too little for 2x birthday gifts?
Should I add something else?

No way! That’s heaps! I usually budget around £10-£15 for a gift. We started off on a higher budget, but once they start school it becomes very expensive!
Thats very generous of you.

No way, maximum of £10 here for school parties!

€50 is plenty sufficient as a shared voucher. I as pp, usually budget £10-15 for gifts otherwise it becomes obscene as children get older and attend more parties.

If €50 is basically the same as £50 that's WAY too much.
I used to never go over a fiver.

Way too much! I would have spent a tenner on each.

Way too much for a school friend.
£10 max budget here.

£10 limit for me at this age
