I was anal... anything that was info only went into one folder (I even had that seperated into trimesters, nursery equipment, hospital info ).

All bills went in with our other bills to be paid but receipts went into a maternity receipt file.

Pathology slips, appointment cards, ultrasound slips went into my diary so I had them when I needed them.

Results went into a results folder.

Contact info was in triplicate - one in my wallet, one by the phone and one in my diary... then there was the one in the car and also the one on my desk at work (just in case I lost all memory in the excitement of things happening and couldn't remember numbers of people such as DH, Ob, Student Mid, the hospital )

Samples went in a little box for if/when I needed them.

HTH!
