MFKAG, your LO is so darling! What a smiler.
Turtle, hope your afternoon off helped a bit. It's quite brave of you, as your DH sounds like mine.
G is waking more frequently in the early morning hours, too. Not sure he really needs a feed everytime, though. Have you tried soothing/rocking/patting before feeding? I do it for a minute or two, just to see if he's really awake and hungry or just fussing. Mostly he still feeds, but hey, worth trying. FWIW, G slept on his side for most of the first three weeks of his life, without incident. I would second trying his side first, if you are worried about front sleeping.
Re: not enough milk. I notice a difference in supply in the evening (G likes to cluster feed) if I have a nice big lunch and a good snack in the afternoon. Not great for trying to lose weight, but definitely good for my milk.
And can I just say, you made a roast dinner?? You deserve a medal.
MB, I hear you about the long stretches of sleep making you feel worse. G did a 6 hour stretch one night and when he did wake up, I felt like I'd come out of a coma. I guess I had fallen into a much deeper sleep than normal, so when I woke up it was more of a shock to the system.
