Hi all
Checking in after a manic few days as all grandparents etc have visited.
Ratbag, great news that you get to see a paed quickly, I know some people that tummy sleep because their babies have to for similar reasons, and it works for them 
Well done Alex on being over 7lbs! And Trish, quality time with H and DH is so important, and a well fed baby (by whatever means) is a happy baby.
As for us, DD pretty much did a 36 hr marathon session, my milk came in Sunday evening, then suddenly at Midnight she couldn't latch on, we had a screaming meltdown at 3am, I caves and gave a bottle of formula. I then gave her to DH to settle and went to bed - I got 3 hours sleep (after going on 36 hrs without more than 20 mins) and baby got 6! I called the midwife before DD woke up, but luckily when she did DD fed. Midwife came, weighed her and did a BF talk with me. Luckily, yesterday DD fed ok, and last night was up 3hrly, so I got 2 x 2 ish hours sleep and then another 45 mins this morning, and an hour thus afternoon 
She had lost weight yesterday (7.5%) but gained a bit today so midwifes were happy. She has also started pooing at day 5!
No one day or night has been the same yet, so I am taking each hour as it comes, and today we tries to walk down the high st, which was a disaster because she wouldn't settle, I tried to feed her in a pub but she wouldn't feed well/ to sleep so we came home where she then slept for 3 hours
I'm hoping we have another good night and please god I get some sleep but will see!!
Re: co sleeping, we don't and i also have to get up, bring baby into living room, arrange cushions, check/change (if dirty) nappy, feed for an hour etc. It is difficult, but we are not set up for co-sleeping. Baby is in crib at end of bed, and it seems so far away
