Vicky - that does help, thanks! And I am humbled that I am whingeing so much after only a couple of weeks of disturbed nights, and you've had 10 months of it!! Sorry!
I think I already knew the answer to my own question, really. The answer is always milk, milk, milk, milk, milk!!
Anna loves crumpets, too - hadn't occurred to me to have them as a breakfast food, though - we only ever have them for Sunday tea. But a girl needs some variety in the mornings, so something other than bite-size shredded wheat or cornflakes to start the day sounds great. We will try it.
