Howdy - I never used one. I actually never heard of one until after I had my second baby. Personally I haven't felt the need to have one - but to be bullied, belittled and laughed about at your baby shower by your friends is awful. Seriously, women can be so nasty. It's a useful item that can only do good things for your peace of mind and the safety of your child. It should be of zero concern and importance to anyone else. Stuff them - you are doing what is right for you and your baby.
