You'll probably find that your need for sleep and your pattern of sleep changes a lot during your life. However, I have yet to become an early riser!
When I was first at university I would usually get up at 10 in the morning. Now I'm up at 5.30am ... it's a habit left over from my PhD days.
But Crickson, what about your little girl? Doesn't she decide what time you get up?
Ha ha, yes mostly she does. At the moment she wakes at about 5am asking for milk, then she goes back to sleep until 7. It's not too bad I suppose.
