My in laws are extremely generous with my children at Christmas which is great, the kids get expensive gifts that they would not otherwise receive. However the whole gift giving becomes a bit of a performance. They give the kids smaller (still very reasonable) gifts and pretend that they have received all of their gifts and the kids say their thank yous etc. Then when it's all done there will be a grand reveal that actually there is a huge present hiding in another room. I think this toys with the kids and teaches them not to be as thankful for smaller gifts they might receive because there is always a bigger more expensive present waiting for them - which 9 times out of 10 there won't be when it is anyone else giving them gifts. They do this if they ever give them money too - give them a fiver which they will be very grateful for and then laugh and say not really and give them another fiver. A fiver is enough and I don't want the kids to then think a fiver is not a very nice treat.
AIBU to ask them to tone down the performance when I know their heart is in the right place and they just want to make the kids happy?
