I don't want to jinx anything, but we have spent the last two days trying to get as much milk in her as possible during the day, and the last couple of nights have been better!
Recently she has been ready for sleep at about 6.15-6.30 and gone to sleep with a couple of oz, woken at about 9.00-9.30 to have another couple of oz, then wake at around 11.30 and from that point onwards sleep is very unsettled with 1/2-1 oz every 45 min or so to have around 6-8 oz, finally waking at 4.30 to do a mega poo and not going back to sleep after 
Last night she fell asleep at 7 with 5oz, woke at 10.30 and had 5oz, then woke at 1.45 and was unsettled until waking at 6.15, however she thrashed less and had about 4.5 oz during this time. Still not great, but getting better!
Think I'm going to continue trying to get lots of milk in her during the day and try to push bedtime slowly later. Fingers crossed we make a bit more progress!
During the night I burp DD by sitting up a little, lying her on my front and rubbing her back quite firmly but slower than I normally do. It can take a little longer but it doesn't wake her. I can then roll her on her side next to me quite smoothly too from that position.
The thought of having another baby anytime soon would be simply terrifying! I think it would be amazing when they are older, but I can barely survive each day with just the one. Before we even started trying we had decided we only wanted one, and I'm very pleased with that decision still!
A few frequent posters from the antenatal and early postnatal boards seem to have disappeared. I wonder how they are getting on?
