Thanks so much for all your replies. I've read them all and taken on quite a few good ideas. I really want to put the time in to respond properly but DD is really sick and I'm tapping away on the iPad in her room between coughing fits and tears.

In short, 3/4 sleeps today he went down with no tears and one nap slept 1.5 hours!! That and having spent a bit of time gardening (which I find really therapeutic) and I'm still knackered but feeling more positive.

Will try and pop in soon post snot-apocalypse. oxoxoxo
