Hi. Im 20 weeks pg and DH and I took a long-ish bus journey earlier on and what with all the vibrations, rattling around, bumpy roads and having to sit on a seat that was little more than a piece of cloth over hard plastic, I wondered if all that shaking around could do any harm? I was literally coming out of my seat at one point and had to get off the bus early. I'm very emotional today (its a sad anniversary for me) so don't know if I'm just being silly but I burst into tears once I stepped off the bus, DH trying to calm me down, and ended up walking the rest of the way home worrying about shaking baby's brain. :(
