How's minimopsy today? Do you have a date for discharge from the hospital yet?
Welcome back AnAirofHope! Nice to see you de-flouncing back to MN! I'm looking forward to seeing the "magic" pictures on FB tomorrow! 
Hope the scan goes well tomorrow, ChipsandSpuds!
HopAlongOn, re the sleep thing, has that coincided with the problems at nursery? They do get unsettled if their sleep is troubled, or if they feel nervous about "being left". How much light does DS have in his room at night? Is there any chance you could leave the door open and move around upstairs (let the bathwater out, wipe up in the bathroom, etc.), or even fold clothes in the doorway? I ALWAYS have a massive pile of clean laundry ready to be folded (since I finish a load and dump it, then use the emptied basket for the next few load s). If he accepts your being near, and audible, perhaps you could progress to having a bath (which is vastly superior to having to fold laundry)...
If the nursery "roughness" hasn't coincided with the sleep-training, then it's just a matter of reinforcement. They need manymanymanymanymanymanymanymanymanymany lessons in this sort of thing, since they're not actually learning, but being trained, and even we adults - though we might seem to pick up facts and skills relatively easily - still need to train to change our fitness, behaviour, mental outlook, etc... (compare knowing Thomas and all his flippingFriends with potty training!) I think DD's "thing" to be trained out of is spilling and breaking glasses - little so and so!
That sounds horrible, Figster - what a nasty combination! 
OiMissus, that sounds an amazing lot of furniture shopping! Very generous of you to let DH have the racecar bed! Some friends of mine had that for their DS, and it was amazing! I was a bit surprised that you're telling your parents so late, but, on reflection, that's probably because family members often seem to get involved in breakups far earlier than they ought to... and you are being so methodical and careful about it all! Just maybe don't let your parents know if you have discussed it with any of your friends (beyond us!) before telling them, as it's unlikely they would understand, or want to understand that, or understand that it really does show good-will to sorting things out with DH, by NOT getting family involved. I once broke up with DH (back when he was a BF, and my mother's "oh, well, let's move on" sort of reaction gave me to understand that she had not been overly keen on him, which was a bit awkward when we sorted things out and eventually got back together. I now make an effort not to sound off about him to her, as I just sort of feel that she might "hold it against him", IYSWIM. By contrast, friends' opinions can be given, and taken, more freely, as friends are NOT your DH's in-laws, so there's no need to preserve a relationship! I hope your weekend revelations go well.
Enjoy the last couple of days with DH, aethel and then DS will have more space in your bed, to starfish out and not disturb you!
Two trips to Waitrose yesterday, to pick up all the "click & Collect" stuff I ordered the other night. Even our estate car couldn't swallow it all in just one gulp! Although it was lighting and ceiling shades, which are bound to be bulky, it was strangely satisfying to have "something to show" for what I spent! So often, a food shop, for instance, will seem like not much compared to the bill! 
DD conked out in the car just as we set off for what turned out to be the first trip, so I had to heave her into a trolley and brace her head as I waited for the packages to be brought down. Every now and then, she would wriggle and complain (probably because her glasses were digging into her, poor little thing), but she carried on sleeping through that, loading the car, the school run, back in the car, dropping them at the new house, and back to collect the second lot of packages! Bedtime last night took aaaaages!
