Eventually toddlers will outgrow their need for a daily nap. Typically, we switch them from a daily nap to napping every other afternoon, and then eventually we stop putting them down for naps altogether.
I recommend parents consider transitioning from “nap time” to “quiet time.” Make that afternoon nap time a regular routine time when the house gets quiet. It can be your family’s own “siesta time,” just like in cultures that live in hot climates. Everybody, mom included, can have an hour of rest. The toddler can choose to sleep or to play, but its “quiet time” and they are expected to amuse themselves in their rooms for a half hour or so.
You might give some suggestions for what they plan to play with quietly in their room today. You can put up a baby gate if there is a conflict getting the toddler to stay in his bedroom. But mom should nap or read too. Its’ easier for your toddler to play independently if they don’t feel they are missing out on things, so everyone enjoying the same quiet time is helpful.
So try whispering it: “Shhhhhh! It’s quiet time, the house is sleeping. It’s time for calm activities in our rooms. Mommy is going to re-group and rest too. See you in half an hour!”
