Naps are developmentally more challenging than overnight sleep. During the day, sleep pressure is lower, sleep cycles are lighter, and environmental stimulation is higher, all of which can make naps less predictable.
Because of this, it’s common for naps to lag behind nighttime improvements and take longer to become consistent. This does not mean the sleep plan isn’t working—it simply reflects how infant and toddler sleep develops.
By prioritizing overnight sleep first and approaching naps gradually, families often see smoother, more sustainable progress over time.
