The following infographic provides a realistic look at baby, toddler and preschooler sleep. Including average night waking, need for night feeds, sleep regression and average amount and timings of naps.
NOTE: This is averages only, some babies will sleep more, some less. They are all different!
The naps are the *total* for all naps combined, not per nap – e.g at 3-4 mths TOTAL naps are 3-4 hours, usually split over 3-4 different naps, so averaging around 1hr each.
