Lydia has colic. Every night for about a week she's begun crying for no real reason. It begins between 5:30 and 6:30 and lasts for 1 to 3 hours. Nursing may help for a few moments, as will walking, swaddling, shushing, swinging or massaging.
The rest of the night and day she's great. But, oh, how I hate the evenings.
