As an expectant mom you are stepping in a 'black box' of baby care, breastfeeding, help resources, advice from everyone (if you want it or not ;-), products and a lot of other things that you wish you had someone else experience what worked and what didn't.
For example think about:
swaddling, nursing, pacifiers, diapers, baby massage, baby carriers, crying, sleeping rhythm, baby gas, ointments, burp cloths, outfit sizes, recovery, bonding, books, CD's, white noise etc. etc.
Do you have any 'I wish I had known that as a soon-to-be new mom?
