Well emc, you are certainly not the only one. 4pm seems to be the trend for many of us over the past 10 days / few weeks. Must be that 6th sense or something weird that we cannot see / feel. Heat most likely, but still weird that our little girl, who was sleeping through and so were her friends, are now waking at 4am. Am giving in and getting up and she feeds well too at 4am. Hey ho - once the weather cools down again, it might all work out again. Musn't complain about the weather though.... Fans, extra blackout blinds, sippy cups - i'm up for anything and will try all tonight.
