I thought it would be interesting to have a thread for all our dhs/dps to give them some advice on dos and don'ts!
I'll go first:
Do bring your dw chocolate/water/whatever she is screaming at you for, without asking her if she should really have that at this time
Don't (REALLY, DON'T) say "It can't hurt that much, women have children every day!" And if you are tempted to say this, don't be surprised if she punches you on the nose
