Kensgirl tell your dh that he's being an absolute plonker from me. Yes, you being pregnant shouldn't stop him from going out occasionally, but not every other night. And you need to go on strike in terms of doing housework, cooking, cleaning and washing (particularly recommend the latter - he'll soon start worrying if he can't find a clean shirt for work!). You've got to get him to realise that your child is a joint responsibility, and it starts now - he may as well get used to helping out a bit now as he'll have to do a lot more when the baby arrives!
Cots etc - we had a moses basket by the bed, but ds grew out of it by about 3 mo and went into the cot by the bed with the side down. We did find rocking really good when he had colic, so might have found the hammock quite good. In terms of travelling, if you go to parents/pil quite regularly, I really recommend getting them to look for a 2nd hand cot going cheap locally, and get a new mattress for it. Its so much better than a travel cot, and my parents got a little toy that attached to the cot that ds recognised and connected with 'knowing where he was' and was very happy - and they can stay in a cot for longer than a travel cot (size and height) so easier to have a better routine for longer when you travel.
Now when we travel we quite often take the mattress from ds's cot (that he moved out of quite a long time ago now) and put it on the floor against a wall with a bit of padding down the open side so its not hard if he 'falls off' (about 3" so not exactly high!) - he sleeps really well on this and we don't have to worry about needing mattress protectors for other beds, or him falling off a bed - although we do have a travel bed guard which I think we'll probably take on holiday this summer.
Survived the party - we ended up with 8 3yo, 1 5yo, 2 2yo and ds. And, with the weather as it has been, the garden was too wet, so we had to amuse them inside - made pizzas, iced buns, decorated gingerbread men, and did some things with pipe cleaners! Pop up house in the hall was a big hit as well. Absolutely shattered, but I think all of the children enjoyed it!
