I know what you mean. When Freya began to sleep better, and I told people she was only waking 2-3 times a night, I received some horrified looks! But to me, that was so much better than before.
Same here, they are not the ones getting woken up, I am, so why should it bother them so much? I have learnt not to say anything to checkout operators as they seem to think that they can dish out advice about sleeping.
