I think this is a "can't see the wood for the trees" question - but here goes.
Ds is a very reliable during the day (apart from when with MIL - but as he won't be that's not an issue)
But is nowhere near trained at night.
So on a plane what do we do as we have no idea when he'll fall asleep? Or do we take PJs and pull ups and have a "bedtime". Or do we put a pull up on him for the whole journey to avoid stress altogether.
We leave here on Saturday morning and arrive UK Sunday morning - so that's 36 hours approx.
