HI!
There is no problem with
travelTravel sickness in early pregnancy. At least no harm to the baby. It may be miserable for your wife, if she is experiencing any nausea and/or vomitting. If she must
travelTravel sickness to get to work, and if she must work, there is not a lot to do! The baby won't suffer any harmful consequences, and your wife will probably figure out how to pack a snack, or whatever is necessary to help her feel OK while she's traveling.
Good luck and congratulations!
Dr B
