Hi Rachael,
You are probably in the UK, but I tried a US version of homeopathic sleep remedy - called Calms Forte and it worked well...I used it for a few days on DS with his NW and it sort of broke the habit I think..at least for the lats 2 days..but when you have a DS like mine, you don't count on this to be forever. but would be worth a short for you.
And its better than Medised since its got no side effects etc.
Also, what I do is with EW, DS and I cuddle up on the couch and just lie there till its 'time' for morning milk etc. At at times he does here and there and it allows me to doze a bit as well. Would this be something you are Keen on? DS uses a pacifier and cuddle his burp cloth and we us that on the couch as well (so he still beleive sit sleep time, only time paci is allowe) . I avoid bringing him to our bed because then he 'enjoys' that a bit too much and thinks its a a game...
Also part of our EW?NW is due to uncomfy nappy, he is in night nappies and oversized one sbut he pees a lot in the night and that wakes him up
