I remember R. Yaakov Horowitz telling me one day that it was quite amazing how many couples seem to feel that it’s okay for the kids to see them fight, but not okay to see them being nice (and even affectionate) to each other.
That being said, Eeees and I have always shown affection for each other in front of our kids — and yes, this includes hand-holding, using affectionate terminology (i.e. “dear,” “honey,”), hugging and even kissing.
