Thanks guys :) I think the reason I'm suddenly less sure about Jacob is coz I've never known any kids personally with that name, whereas I know a gorgeous little boy called Toby and think of him every time I hear the name! I'm sure that soon enough he will define the name and help me love it, coz in principle I really do like it! It doesn't help that he still looks a bit like a monkey... 
Travelling/moving house across the world sounds terrifying. We're attempting to sell our place and buy a bigger one, and if we get the house we'd like then our move basically will consist of moving a few streets away, yet I'm still absolutely dreading it if/when the time comes!!
Also, yes biting is perfectly normal, don't worry too much about it, as others have said try and give your older child more attention than you think they deserve for biting your helpless baby and yes think of the analogy of your hubby bringing home another woman or something. I'm still impressed with how well my DS1 is dealing with the twins though am fully expecting things to change once they're mobile and nicking his toys, etc!
Dreaming, it sounds like you're doing really well. Keep it up, you're stronger than you think :)
rednellie it's nice when they're the same weight isn't it! Mine were exactly the same down to the gram when weighed last week, couldn't quite believe it... of course that meant that the midwife was still a bit 'ooo err Toby's still not that heavy, better weigh him again soon' (he was the bigger baby.) All a bit ridiculous when you think about it!
