Phew, yes we are all home now, thank you so much for thinking of us!
Both gremlins ended up with NG feeding tubes on Wed night as they weren't keeping enough fluid down, and they left the tubes in till yesterday. We were all discharged yesterday morning then just as we were getting ready to leave Mercedes did a massive explosion all thru her cot so they decided to do a sample of it to check for lactose intolerance and it came back positive. So she is back on the Neocate again

It may be just a temporary thing but the doctors do suspect that the switch to normal formula a few months ago might have something to do with her poor growth.
So my poor gremlins spent their first ever night apart last night, they didn't fret too much, Willie said Sienna was too glad to see her own cot to care whether Mercedes was there, and Mercedes kept looking around for Sienna but settled pretty quickly.
Discharged this morning, poor Mercedes is down to 8.2kg
Huge thanks to Deborah and Fiona for visiting and to Fiona for keeping me in home cooked meals, and to everyone who sent me texts to stop me getting bored.
Man it's good to be home!
