shazza minimise any jostling and movement? Was this fella born around 1820? Did he tell you also that you should be laying flat for the next 9 months? It is really not going to fall out ... Exercise is fine (and healthy for mum and baby), as long as you are not going sky diving, horse riding (because of risk of falling), skiing etc. You're pregnant, not terminally ill! Besides a holiday would relax you, which can only be good. Also I think you should make full use of Couple Time now that you still can!
I wouldn't book a holiday to cycle a Tour de France stage in the Alps or to go hiking in Alaska, but a normal relaxing holiday ... I can't see why this would be a problem and I am positive GP and midwife (would there be such a thing as a midman?) would agree.
Looking at that site you suggested at work is perilous full stop! It has lots of fetus type pictures! My work must've cottoned on by now anyway with my google behaviour.
The litter is good I think. If these kids are as quiet after they're born as they are now, we will be quids in. Not sick at all, maybe a bit breathless. Occasional spell of being incredibly hungry. Occasional bit of spotting. But that's it. So I am still not entirely sure they will find something in there at the 12wk scan, but what can you do but tough it out. DH does reckon I have started showing. I know what he means, there is definitely something starting to stick out, but I am just not convinced yet it is not the healthy appetite rather than the twins. I may have to get measuring tape out. Also, not sure whether it qualifies as a craving, but I really could eat oranges and drink orange juice all day. They'll come out orange at this rate.
