Notsoold I thought DD was going to love being swaddled and the fool that I am, I bought her a lovely merino one, and did she like it? Did she hell! She was like an angry Houdini, furiously fighting her way out every time we wrapped her up in it. Our bedroom was very cold last winter, and can remember the gro egg thermometer turning blue in the night and doing its sad face telling us that the temp was below 14c or something. I think one thing that helped was putting a sheepskin in the cot, then a sheet on top and then she lay on that in a grobag (merino!) plus a cellular blanket or two. Can remember her alarming habit of pulling the blanket over her face, but doesn't matter so much with cellular.
Rosie am really glad you've got your trip sorted. Sounds like there will be good and bad bits, but once you are on that plane you can just focus on the trip rather than preparing for it! The most important thing of course is that you have some internet access that you can vent to us every eve when DP has disappeared out and your SiL is trying to feed the baby 
BBD well done on the tidying - we had a big blitz yesterday but it's never quite enough in this house! And good idea re swapping the toys around!
Exhausting day here yesterday - both siblings visited with their partners plus 2 nephews. No space to sit them all at the table for lunch, but we managed but having overflow area in the lounge. And I managed to cook something that suited everyone's varying tastes! Older DN (12) has Asperger's and up until the summer had progressed well in a good primary school. Then he went to mainstream secondary and has utterly floundered and been refusing school since Oct. Poor DSis is beside herself as his mental health is declining and he spends every day in bed now. He refused to come out for a walk with us yesterday and had a screaming fit once he'd been pushed out the front door. It's so, so difficult as there are things (such as school) that he has big, genuine issues with, but also things (such as walking to the park) that he just can't be bothered to do, but the outcome (screaming fit) is the same! And at what point do you let his wishes take precedence over everyone else's in the family? Btw, they're getting very little help and support at the moment and can't see that changing much in the future. DP and I started saying to ourselves how lucky we are that we don't have this sort of problem to cope with, but actually it's too early to say that and ASD does seem to turn up somewhere in every generation of my family.
