I didn't get the NHS book with my first as they'd run out (he's now 20mo) so I made sure I asked for it with my second as I wanted to know what was in it!
Also got invited to parentcraft classes - what has my HV been telling people, I wonder?!
Mercy, I agree, there'll be a new study out in the future that says x or y is also bad - but it's more likely that more things will be added to the list than things will be taken off it, isn't it? They're not suddenly going to decide that vitamin A in large quantities is actually OK for unborn babies are they?
