My mil does this every year - asks us ridiculously early what we want for christmas. But the other day she came round and actually asked the kids (aged 6 and 4) what they wanted from santa and started talking about writing him a letter etc.
Now AIBU that it's far too early for kids to start thinking about this as it just drags christmas out for a long time (and they change their minds nearer the time anyway!)
She doesn't need to save btw she just likes shopping without all the queues and hassle. She says she hates christmas and will only get the kids 1 present each and then arrives christmas eve with a bin bag of presents EACH!!
