How to thank for present when i dont know what gave what?

[Koumak]

Dilemma
So we had this birthday party which others me not so sure as very chaotic?think was great BUT my ds managed to open most of his presents without me there (fathers don?t seem to be reliable when it comes to such important tasks) so now I have no idea what gave him what and he got some amazing and expensive presents so I feel I should really thank everybody properly and personally. But what do I say on the thank you cards or should I ask the parents (mostly ds?s friends from nursery) btw what did you give my ds??? It seems rude but also so does not thanking everybody properly. Please help.

Just send a card saying 'Thank you for coming to my party and for my fantastic present' - that will be fine. And make sure next time that someone oversees the present opening and makes notes!

You could either put on thank you card something like 'Thankyou for the wonderful present' or you could ask - I once got asked what we had given for a Christening as their elder dd had opened everything in the corner without anyone noticing. I wasn't offended

I know exactly what you mean, especially about fathers not quite getting it.

However I do think that a thankyou note is an important gesture, even if you can't do it in exactly the way you'd like to (ie tailored individually to thank for specific things)

For DS I printed off little slips in a pretty coloured font that said "thank you for coming to my party and for my lovely present. I had a great time and I hope you did too".

Then DS stuck them on to postcards, and added decorations. he signed his name and wrote the name of the guest.
You can always start a conversation with each person and hope that some clues come out which lets you know who gave what!

the thing is i work fulltime so never get to drop off or pick up so frustrating so cant casually bring it up i dont want to offend anybody...

You're going to have to go for the 'Thank you for the wonderful present' option, I think - it's a lot better than nothing.

..and next time be fiercer firmer about presents not getting opened without the presence of a reliable list maker

shouldve been who gave what nevermind...
thank you all for your help
