OMG I was just speaking to my girlfriend about this yesterday.
What a freaky coincidence!!

She thought it was written in her Yellow (or Purple now) book that you get from the hospital. But it works out it was only her blood type, which is all I have too.
I was told by the midwife (during the guthrie test where they ***** the foot) that you usually don't get told the blood type anymore unless for a specific reason, as there is no need for it. Because if a situation came up where you did need to know the blood type your child is, they wouldn't take your word for it anyway and do a test on the spot.
I hope I am making sense with my ramblings.

I am so dying to know my children's blood type as they could be anything with the two of us both A and the other B with the recessive O.

How did others get the guthrie results with your child's blood type on it too? Posted out to you or what?
