Huh? I'm sorry, but I have been pregnant with 2 babies, one weighing over 10 lbs and one at 11 lbs at birth and each 22 inches in length. Even at that size, when I was 'kicked', it didn't jar me so much as to make me forget things or lose my train of thought mid-sentence. I think this is far-fetched.
I do agree with the honey vs. vinegar theory and I do believe in killing them with kindness, but to say that being pregnant warrants special treatment (aside from what is physically too demanding) is too much.
Relating to the original post---I have found that a direct approach to immature behavior (such as gossip, bullying, etc.) has worked best. Any time I feel like I have been spoken to in an inappropriate manner, for example, I keep eye contact and say something like "I'm sorry, what?" If they repeat what they said, I continue to say "Please do not speak to me in that way." Simple, direct and polite.
