This is a bit of an odd one but it's been really bugging me. Every time I visit the hospital for a scan or my GP's to see my midwife I see pregnant women carrying a sort of plastic pack/folder thing. They are all the same, A4, with a slider top thing to close them like a food storage bag, they have coloured squares on the back...and I'm just wondering what these are? Am I missing out on an information pack being given out somewhere?
Thanks to anyone who can shed some light on this for me!
