hi there,
we actually went away with close friends when we were very newly pregnant and not ready to tell... We knew they'd figure if I didn't have a wine with dinner. So, our plan?
I had the wine, but during the night my husband and I would swap glasses. DH would just casually take over my glass at some point. No one ever noticed!
Surprisingly simple, but it worked. It even worked at numerous family dinners too!
Hope this helps!
