No time to post these days! I am trying to keep up with reading your posts but with my babybrain I do forget what you've written almost immediately 
But bethy your poor DS1 that is a dreadful thing to have to put your son through, I can't imagine it
I suppose at least he is old enough that you can explain why he has to fast, still it will be very difficult indeed
for you both. And yes, it certainly does put in perspective our worries about missing one dinner. (Which DD1 did last night and I surprised myslef by not giving a monkeys - there's sleep-deprivation induced apathy for you!)
Both my girls are asleep
I'm expecting one of them to wake up and bother me any second.
DD2 still has night and day confused, she tends to wake 6pm ish, cluster feed all evening and refuse to go back off until 1am. I am trying to get to bed 9ish and get in a couple of hours before DH brings her up with him but there always seems to be so much to blimmin do in the evenings I don't always manage it.
Tonight I'm due to go out for a meal with RL toddler mum-friends, I'm going to go although I have to say evening socialising is the last thing I feel like doing at the moment. And taking DD2 with me as we've only tried her on a bottle once, and she spat it all out (twas formula not EBM, I really can't see when I am supposed to find time to express. Instead of catching up on MN I suppose).
Apologies for me me me post. I keep telling myself, the newborn phase won't last forever. It won't last forever. There is light at the end of the tunnel....
PS PA you seem to be doing brilliantly, I feel I am only just keeping head about water and some days not even that. I think your DS is about 3w older than DD2, maybe in 3 weeks time I'll be ok?!
