When all else fails, many parents buckle their infant safely into their car seat and take them for a slow drive. Often the hum of the engine and the motion of the automobile will lull them to sleep. Turn your heat on low to get it slightly warm in the car and see if your daughter doesn't quit crying and nod off.
Busy moms and dads know all about the soothing power of the infant swing. Whether the baby is bored, colicky or overtired, the back-and-forth motion of the infant swing often produces a gentle rhythm that she loves and puts a smile back on her face. A slow setting is best so as not to startle or upset an already unhappy baby.
