Blow up beds are fine, dd was going to be sleeping on one in ds's room, the trouble is ds (3 next week) isn't in a bed yet. Fortunately we have just got one but it is currently in dd's room. So this weekend we now have to move it into his room, dismantle the cot and get him used to sleeping in a bed. Plus dh's computer, shredder etc are in the office and ds has a nack of buggering up such equipment, so dh will have to take it all out and store it somewhere else for the night.
As I said previously we originally believed she would be abroad for christmas, but in any case she lives with her other daughter who is hosting christmas for other members of the family and her husband's family so it isn't a poor little old lady sitting alone in her home on christmas at all.
