hi RK, didn't realise it was you!!
i'm sure you know this being a mum yourself (and i'm not, yet) but i found that dry, carb-y things like toast and crumpets worked wonders for 'morning' sickness! cream crackers, although they taste like a dry leper's scab, also work well.
to be honest, i would be inclined to just let her get on with it. for the first sixteen weeks or so of this pregnancy, i got up at about 8 then went back to bed for a lunchtime nap because i was so tired! sometimes i'd spend whole days in my pj's!!
so you know "nothing" huh? yeah, because you've obviously never been pregnant!! have you got her one of those pregnancy books which list the 'minor' ailments of pregnancy? i can heartily recommend dr miriam stoppard's "conception, pregnancy and birth". I borrowed it off a friend but i'm sure you can get it from the library. even though it does list these ailments, you might like to go into some finer detail about heartburn, constipation and spotty skin (three things that i've really struggled with, and this is a relatively easy pregnancy apparently).......
ooh, this turned into a bit of a ramble, sorry. hope you're keeping ok runkid, take care. xxx
