I gave my mother (child's granny) a specific toy idea for my son's Christmas gift- something that was amongst a list of about 4 things he's keen on. Since that time he's started talking about this one toy a lot, and seems even more keen / hopeful it might be under the tree.
Difficulty is that we are not seeing Granny until the 27th, so on the day itself he'll have other lovely things to unwrap but not the special toy.
If I'd known how much he had begin to like this toy I might have bought it myself and let Granny get something different since she won't be seeing him on the day itself.
She's already bought the toy and is looking forward to giving it to DS on the 27th.
Other than saying "ooh perhaps Santas been to Granny's home too" how can I manage his (potential) disappointed reaction on Xmas day at not getting the one toy he wanted but without saying "Granny's got it" and spoiling the surprise for them both?
