My DB/DSIL have form for being incredibly tight with money when buying gifts for my DC whilst expecting far more for their own DC. We each have two DC. Their income far exceeds our's and their outgoings are far less ( we know for a fact as they have told us). Every Christmas and birthday we ask what their DC might like so we do not duplicate etc. We want to buy their DC something that they will like. Their suggestions are about the £25 mark which we are happy to pay. This however, is not reciprocated. It was recently my DDS birthday and tbh, I was disappointed with the gift they bought. It wasn't even age appropriate (think Peppa Pig for a ten year old girl). To add insult to injury, my SIL told us what a bargain this gift was for £4. I was brought up to be grateful for any gift and I have tried to instil this into my own DC but tbh, I am struggling with this one.
