Hi Kat I left you guys for a few hours and you all went crazy posting!
I had my non-id boys at 29+1 weeks due to spontaneous labour. In NICU for 8 weeks, one was over 5lb and one wasn't. they were the tiniest things ever!
They are now 2.8yo and you would not believe they had such a shaky start. I was still at work when i went in labour, so all a bit of shock. natural del though, head down and bum down.
I agree with whoever said, wake the sleeping twin while feeding, so that they gradually get used to being hungry together, and also try and get to grips with tandem feeding (I bottle fed) else you will feel like you are constantly feeding. I was pulling my hair out in the first few weeks after getting them home, until one day i got myself comfy on the sofa, lots of cushions and fed them together. Meant I got a good 3 or so hours between feeds.
Oh and i may be shot down for this, but routine routine routine. Not rigid, but loosely round 3/4 hourly feeds and try and plan at least one trip out the house a day. With two it's far harder to go with the flow, as I had one fussy baby and one chilled baby....however, you will fin all this out when they arrive.
