This is a real moment of “no shit Sherlock” that 3/4 year olds don’t want to be shlepped around a mountainside in 10 tonne of ski gear that isn’t the frothy frilly crap they are usually in. They’ve just spent 10 hours in a plane, in a completely different environment, culture, temperature, etc and are now being rushed out the door to do what mum and dad want. Just let them play for a bit in the morning, settle in, get them to walk up the hill instead of being pushed in the pram, take them to get hot chocolates and go play in the snow. Let them be kids!
I must have missed the part where this was going to be a skiing holiday, I thought it was just a trip to Japan. Not a holiday planned around an activity that doesn’t exactly gel with having little kids.
