Hi Clappedout
I think that weight gain sounds fine - after all, when they're that tiny, they only have tiny tummies, so can't fit too much nourishment in at a time. To be honest, I'm expressing less now too as Rosie is also getting better at BF - also, she's not so tolerant of being put down at the moment, which makes it difficult to express anyway. Managing twice a day at the mo, which is enough to keep up the amounts she needs for supplements.
Providing you're making enough milk to keep Otto happy and he's feeding regularly, I should think you're fine to express less - and the supply should adjust as he gets hungrier as well. Although it may be worth expressing once a day, just to be on the safe side...
I was told to relax the 2.5 hour feeding regime once Rosie got to 3kg, but I've already eased up. Her appetite is better, so I'm letting her determine when she needs feeding - if I stick rigidly to the 2.5 hour timetable, it either takes ages to wake her up to feed if she isn't ready or, if I force her when she's not hungry, she just throws it up again. It feels a bit easier now... still full on though, very impressed how your managing with a DD too!!
I guess what I'm saying is, the advice of HVs and HCPs is obviously valuable, but it makes sense to tune in to what our babies need in order to make it work for them.
At least the noisy sleeping means we don't keep having to check they're still breathing, eh?!
