Just managed to catch up with the thread. Sending big hugs and 
to all struggling with non-sleeping and reflux, colic etc, especially flyer sorry you seem to be having such a hard time - no extra advice but seem like some good suggestions been given on here.
It makes me realise that T is generally quite good, even though he does do the cluster feeding in the evening and has a bit of reflux which makes him unhappy, but its generally manageable. Going to try gripe water too.
I have to say that DD (my first DC) was actually one of those very rare babies who literally never cried, settled herself to sleep and would be left for hours happily just looking round or sleeping. I'm not saying this to annoy anyone or to be smug, just that those babies do exist and i was very lucky to have one (even though at the time i didn't realise it). And rest assured that the downside was that when DS1 came along, I had such a shock and found it doubly hard because he was a 'normal' baby and cried for hours, had colic, was awake all night etc which i just hadn't experienced before - it was so hard in contrast.
I have also had the numb bladder thing - apparently you get some numbness like the numb skin on the outside after a cs, where the nerves were cut which is why often you can't feel it until v full. Assuming this will disappear as sensation comes back?...
Hope everyone has a good weekend.
