Well actually, when Alex had colic, the MCHN and my lactation consultant told me to put my finger in the brandy bottle and let Alex suck on it! It certainly helped with the colic....
My DH used to bring me a Baileys at about 9pm each night, which would be coming through the bmilk at 10pm feed, which also helped Alex sleep... mind you we only did this when he was really unsettled.
He seems okay now!
