ploom that's annoying about the KA. I suppose excessive growth is probably something most drs would first react to with "let's wait and see how things are in six months" (like my hormone problems), but you still want the dr to take you seriously
. Does your DH have a colleague he could ask informally about it - my DH occasionally asks the consultant at the hospital when I can't be bothered to go to the KA with DD myself?
English I've also thought that our parents' attitudes sound very similar from what you've said (dummy snobbery, etc). 
re the tv thing: I read the Aric Sigman book "Remotely Controlled", which is unequivocably negative about the effects of tv, but then he seems to be an old-school, "life was better in the 1950s" type. Iirc he does respond to the "I watched tv as a child and I'm okay" argument by saying that children's programmes have changed, and that slow-moving programmes are far better than the frantic stuff you often get nowadays. I'm sure the book is backed up by research, but of course you never know how much cherry-picking has gone on with these things!
I prefer DD to watch dvds, partly because it means she's not exposed to advertising, partly because CBeebies is sometimes too brightly coloured and frantic for my sensibilities at least and partly because it prevents us slipping into the habit of watching at the same time every day. Atm she mainly watches Peppa Pig, 64 Zoo Lane or Kipper.
I wouldn't judge anyone who was pg, ill or who had a small baby for letting their kids watch a lot of tv. I do wonder though about the consensus on the rest of MN that tv is absolutely fine for kids and anyone who suggests otherwise should be flamed
