took me ages to read all your posts. Will have to make this post fast as Anya is getting bored of her bouncer.
Very
of all you that are getting 4 hours at a time or even have a day/night routine!! I am letting Anya dictate waking and sleeping times as I don't see how I can force her to sleep. She is currently sleeping in the evening then awake from 11pm till about 4am then she sleeps till about 7 has a quick feed then off to sleep again till 10am then another quick feed then we both get up and start our day at midday-ish.
[incoming typos as Anya is now feeding and I'm typing 1 handed]
K, I tried expressing to have a break but gave up during the growth spurt- she was just on my boob too much that the thought of then pumping them was too much - my nipples needed the break. Now she is feeding slightly less I feel like my boobs have 1 extra feed in them per day so express a bit to make me more comfortable. For Anya at 3 weeks a feed was about 2 to 2.5oz. I tend to store them in bags of 2.5oz atm as breastmilk is very precious and hate to have to throw any away. Remember milk comes faster from a bottle so babies might overfeed then throw it up _ Anya managed to down 4oz at 3 weeks but then it all came back up, after that we limited it and then winded her to give it time to reach her stomach then see if she still wanted more.
RE swapping boobs - I'm really confused about this as people keep telling me different things. One MW told me that I should think of each boob holding 1 hours worth of a feed. If she comes off my boob then wants back on within the hour she started feeding I should give her the same boob. I read elsewhere that after she pulls off and has been winded she should be offered the other breast. After a few instances of very green poo I googled and read that this was probably due to her not spending enough time on the one boob
. I'm back to using the boob an hour principle as at least her poo isn't green any more 
Think Anya has a touch of Colic - as a newbie to parenting and babies I have only just learnt what this is so have stopped giving myself such a hard time when I can't comfort her. She sometimes cries for half an hour none stop and usually it is in the early hours of the morning when I'm desperate to sleep myself which has been known to bring me to tears too but I'm hoping that now I know it isn't my fault I might be able to cope better. 
must stop typing now as my arm is aching
and I managed another monster post!
