The fourth nap is usually dropped between 3-5 months, usually closer to 5 months. Often this nap is dropped when baby transitions to a 4 hour eat/activity/sleep routine although baby may be ready to drop this nap before he is ready for this. Before this nap is dropped, it usually turns into a catnap by, if not before, 3 months of age.
Often the timing of this nap occurs during a baby's fussy time of day so getting this nap to occur may be difficult for some babies during the early months, especially if they have not gotten enough sleep during the day resulting in overtiredness or if they have colic.
