The thing that baffles me is that she had to buy lights for the bikes in case she went into labour at night. So basically, she doesn't normally use the bike for travel, but was making a point. Which I find kind of pointless.
I gave up cycling for commuting around 6 months, but then went back to doing the occasional ride when I was 8 and 9 months pregnant. I felt much more mobile on the bike, which was good. But found that my asthma and reduction in lung capacity affected how much I could really do.
Wee'un had his first ride at 5 weeks in papoose on New Year's Day - figured there wasn't much traffic then. He seemed to like it (well, he likes any sling and just fell asleep).
ps - if i'd cycled to ERI, he'd probably have been born at Cameron Toll!
