My 6mo DD has always been a bad sleeper, she won't nap at all in the day without a huge fight and sometimes not even then. Even as a newborn she barely slept at all. Whenever she IS asleep we have to tiptoe around as the slightest noise wakes her up. We don't flush the toilets, run water, shut doors, sneeze, cough, go to the fridge, open cupboards etc. Its such a battle getting her to sleep in the first place that it would be madness to do anything
to wake her up iyswim.
We live in a semi and depending on our neighbour she can wake at 5am or 9am and that sets the precedent for the whole day, although our neighbour is lovely and not overly noisy but even him running his tap wakes her up!
I remember a MW in the hospital saying to me "they have to fit round your lifestyle not the other way round" and I agree but at the moment we are totally dancing to her tune.
She just has so much energy but also gets tired and cranky but just won't sleep unless it is deathly quiet. Short of moving to a shack in a forest and becoming elective mutes what can we do??
