I personally think that anyone that does this (action) has good intent. I am well over pregnant women, and how good or clever they feel. These days I think that anyone that is pregnant seem to feel that they are doing something, or experiencing something, that is sort of unusual or special. Any idiot can become pregnant-----it is sort of a base thing to achieve. Why anyone would want to "feel" the infant in the womb", is beyond me. Boring.
Interesting enough to answer the question twice though. :P Yes, most women can get pregnant, some of them easily, some of them even by accident. Some actually have to try for a long time before it happens for them, waiting for months or years, some with expensive or painful medical treatment to help the process along. I can see why it's not important to someone not connected with them, but to the pregnant woman herself of course it feels like a big deal. It's a life changing experience. It changes you physically in a lot of ways, some of them permanent, and the hormones and anticipation of having a brand new human being to care for can make it quite an emotional rollercoaster. Have you not had a baby yourself, Fran? Perhaps you have loads of them and that's what made you eventually so jaded about it? Or perhaps you have been around some pregnant women who got a bit carried away? You don't have to answer of course, I just wondered.
I have two kids, and for me both times pregnancy was an incredible experience (sometimes annoying, uncomfortable or painful, sometimes exciting, sometimes scary). Clever, no, but of deep personal significance. I totally get why people close to the pregnant woman (like the baby's father, or grandparents) might want to feel the baby move. That can also be very exciting for young children who are curious about how babies grow, and especially older siblings of the unborn child. My two year old was fascinated to see and hear her unborn baby brother move, and to listen to his heart beat with a stethoscope. That's not to say that you should go around touching pregnant women, certainly not without permission, I just can see why some people want to.
Have you heard the Garfunkel and Oates song "Pregnant Women are Smug"? If not, have a look on Youtube, it might amuse you.
