I'm 38 weeks, and I've heard a couple of times now from MWs things like "that's a good size baby" and "you've got a lot of baby in there". What does this mean? How much can they tell about the size by feeling? I don't think I have a particularly large bump -- there have still been some people who acted surprised I'm pregnant (!). But now I'm getting worried I'll be pushing out a whopper in a few weeks time...
