I would like to chime in as a former fallen away Catholic and total ignorant slob. I would have been one of the buffoons that would have made a dorky comment. Probably not a comment about getting tubes tied but I would have said something rude like “whoa baby you’ve got your hands full already don’t you?” then laughed.
Sadly, it wouldn’t have occurred to me to say “congratulations”, looking back I carry shame. Praise God I was blessed with grace and was able to conceive many children of my own!
I share this only because having been on the other side, I urge KINDNESS when and if dealing with people like this. If someone had smiled kindly at me and said “We really are very happy!” and smiled at me I hope it would have drawn me in, or at least planted a small seed. Sometimes happiness is contagious. I think that would have been better than someone telling me off. Man I was blind, wow.
