OOOOhhhh I have to say i have been guilty.... and i have been on the recieving end The first preganancy was worst for me, but after that I have taken it in my stride. Think of it like this??? most people are well meaning and excited (there will always be the sticky nose who you have'nt seen for ages and someone who just wants a LOOK!!!).. its always easier to be more excited about someone elses birth than your own you don't have the aches and pains, HB, MS, millions of toilet stops and sleepless nights to contend with, a baby brings out the good and bad in most people.
My advice make sure you put them to work for you!!!!
