being awake for 2 hours from 4 am is not ok as far as I am concerned... I feel for you Naomi if that is what you are coping with!!!
Fortunately our 4am wake-ups seem to have settled down a bit - in the last few days while Baileys been sick he's slept to about 6-7am, hoping it stays this way But I feel your pain Bella, being up all night just sucks, and I always feel like wreck for days after. Baileys sleep was better before he turned 1. He used to sleep from 630pm through to 2 or 3, then resettle pretty quick and sleep until 7am-ish. For a few months now he wakes at 11pm-ish, then a few hours later and inevitibly spends a fair chunk of the night in our bed - otherwise we are up and down constantly. Sometimes he is restless only an hour or so after bed time. Oh well, not much we can do - that's they way he is.
