How to word thank you cards when cards got mixed up

[MomtoNico]

My son opened the birthday gifts but the cards got mixed up and we don't know who some of the presents came from. How do I word the cards? Thanks

Thank you so much for the wonderful gift! I'm so glad you could celebrate this birthday with us! Eta some personalized detail so you don't come across lazy and generic. Just skirt the gift part.
