I still remember when my wife had morning sickness and she was vomiting or feeling nausea in the morning.  It's actual quite bad to get.
Yes, it can be quite awful. Thankfully I didn't experience it with either of my pregnancies. Could you do anything to help your wife?
There is limited evidence that ginger helps - so I gave her a lot of ginger candy to eat during that time.
I'll have to remember that! Did the morning sickness last throughout her pregnancy, or just the first trimester?
It was just the first trimester - usually around the 4th and 16th week of pregnancy.  But I've read that 10% of women still have morning sickness after 20th week of pregnancy.
Ugh! That would be rough! Those poor women!  I wonder why some experience morning sickness and others don't?
That's a million dollar question - no one really knows.  Some have proposed theories that it is caused for evolutionary purposes.
That's an interesting idea!  I guess it's more complicated than one would think.
